What Is Neonatal Abstinence Syndrome
Neonatal abstinence syndrome (NAS) is a group of conditions that occur when a newborn withdraws from substances, most commonly opioids, that the baby was exposed to in the womb. When a pregnant woman uses opioids or receives medication-assisted treatment with methadone or buprenorphine, these substances cross the placenta and the developing fetus becomes physically dependent. After birth, when the supply of the substance is abruptly removed, the newborn experiences withdrawal symptoms that constitute NAS.
NAS is not a disease in the traditional sense but rather a predictable physiological response to the cessation of opioid exposure. Understanding this distinction is crucial for parents, particularly mothers in medication-assisted treatment programs, because NAS is an expected and manageable consequence of the treatment that kept both mother and baby safer during pregnancy. At Trust SoCal, we prepare expectant mothers for NAS before delivery so they can be informed advocates for their newborns.
The severity and duration of NAS vary considerably depending on the type of opioid exposure, gestational age at delivery, maternal dose, polysubstance exposure, and individual infant factors. Some babies experience mild symptoms requiring only supportive care, while others need pharmacological intervention and extended hospital monitoring.
NAS is not a sign that you failed as a mother. It is a predictable, treatable condition that occurs because you chose evidence-based treatment over untreated addiction, giving your baby a significantly better chance at a healthy life. Trust SoCal clinical team at (949) 280-8360 can help you prepare.
NAS Statistics and Epidemiology
The incidence of NAS has risen dramatically alongside the opioid epidemic. CDC data indicates that NAS increased approximately fivefold between 2004 and 2016. Understanding these statistics helps contextualize the condition and underscores the importance of specialized prenatal and neonatal care.
- Approximately 7 out of every 1,000 hospital births in the U.S. are affected by NAS
- NAS incidence increased from 1.5 per 1,000 births in 2004 to 8.0 per 1,000 births at its peak
- Hospital costs for NAS-affected newborns average $22,500 per case, with 80 percent covered by Medicaid
- Average hospital stay for NAS ranges from 7 to 30 days depending on severity and treatment protocol
Substances That Cause NAS
While opioids are the most common cause of NAS, other substances can also produce neonatal withdrawal syndromes. The clinical presentation varies by substance class, which influences monitoring and treatment approaches.
- Opioids (heroin, fentanyl, prescription painkillers, methadone, buprenorphine) are the primary cause
- Benzodiazepines can cause neonatal sedation and a distinct withdrawal syndrome
- SSRIs and SNRIs may cause neonatal adaptation syndrome, which is generally milder than opioid NAS
- Alcohol exposure causes fetal alcohol spectrum disorders rather than classic NAS
How NAS Differs from Fetal Substance Exposure Effects
NAS specifically refers to the postnatal withdrawal syndrome and should be distinguished from other effects of prenatal substance exposure. Teratogenic effects, growth restriction, and neurodevelopmental impacts are separate clinical considerations that may or may not accompany NAS.
- NAS is a withdrawal syndrome occurring after birth, not a developmental disorder
- Fetal growth restriction may occur independently of NAS
- Neurobehavioral effects of prenatal exposure are studied separately from NAS withdrawal symptoms
Recognizing NAS Symptoms in Your Newborn
NAS symptoms typically emerge within the first 24 to 72 hours after birth for short-acting opioids such as heroin or fentanyl. For longer-acting medications including methadone, symptom onset may be delayed to 48 to 144 hours after delivery. Buprenorphine-exposed infants generally show symptoms within 36 to 60 hours. Parents who understand what to watch for can partner more effectively with the neonatal care team.
Symptoms of NAS affect the central nervous system, gastrointestinal system, and autonomic nervous system. The constellation of symptoms ranges from mild irritability and feeding difficulties to more pronounced tremors, seizures, and failure to thrive. The specific combination and severity of symptoms guide the treatment approach.
Central Nervous System Symptoms
The central nervous system effects of opioid withdrawal are often the most visible and distressing for parents. These symptoms reflect the hyperexcitability that occurs when opioid-mediated inhibition is removed from the neonatal nervous system.
- High-pitched, inconsolable crying that is different from typical newborn cries
- Tremors and jitteriness, often exacerbated by handling or stimulation
- Increased muscle tone (hypertonia) and exaggerated reflexes
- Disturbed sleep patterns with frequent waking and difficulty settling
- In severe cases, seizures may occur, typically within the first 10 days
Gastrointestinal Symptoms
Gastrointestinal dysfunction in NAS can significantly impact feeding and weight gain, making nutritional support a priority in management.
- Excessive, uncoordinated sucking with poor feeding efficiency
- Vomiting and regurgitation after feeds
- Loose or watery stools leading to potential dehydration
- Poor weight gain or weight loss in the first week
Autonomic Nervous System Signs
Autonomic dysregulation in NAS affects temperature control, skin appearance, and respiratory patterns. These signs help clinicians assess the overall severity of withdrawal.
- Excessive sweating, particularly noticeable on the forehead and palms
- Nasal stuffiness and frequent sneezing
- Skin mottling or flushing
- Yawning and mild temperature instability
When to Alert the Care Team
While the neonatal team monitors for NAS symptoms, parents play a vital role in observing their baby between assessments. Knowing when to alert staff ensures rapid response to changing symptoms.
- Alert staff if your baby seems unable to be comforted despite swaddling and feeding
- Report any new tremors, jerking movements, or stiffening episodes immediately
- Note if your baby is consistently refusing feeds or vomiting after every feeding
- Track whether your baby seems to have significantly fewer wet diapers than expected
NAS Assessment: Finnegan Scoring and Eat, Sleep, Console
Accurate assessment of NAS severity is critical for guiding treatment decisions. Two primary assessment approaches are used in neonatal units across the country: the traditional modified Finnegan Neonatal Abstinence Scoring System and the newer Eat, Sleep, Console (ESC) approach. Understanding these systems helps parents follow their baby progress and participate in care decisions.
The choice of assessment tool varies by hospital, and both approaches have demonstrated clinical validity. However, the trend in neonatal medicine is moving toward the Eat, Sleep, Console model due to its emphasis on functional outcomes and its association with reduced pharmacological treatment and shorter hospital stays.
Ask your delivery hospital which NAS assessment protocol they use. Understanding the scoring system helps you participate in your baby care decisions and communicate effectively with the neonatal team.
The Modified Finnegan Scoring System
The modified Finnegan score evaluates 21 signs and symptoms of neonatal withdrawal, assigning weighted points to each item. Assessments are performed every 3 to 4 hours, and scores are used to determine when to initiate, increase, decrease, or discontinue pharmacological treatment.
- Scores range from 0 to 45, with higher scores indicating more severe withdrawal
- Pharmacological treatment is typically initiated when three consecutive scores are 8 or above
- Medication weaning begins when scores remain consistently below 8
- The system requires trained nurses and can be subject to inter-rater variability
The Eat, Sleep, Console Approach
Developed by Dr. Matthew Grossman at Yale, the Eat, Sleep, Console (ESC) approach focuses on three functional assessments rather than detailed symptom scoring. This method prioritizes the infant ability to eat adequately, sleep for at least one hour undisturbed, and be consoled within 10 minutes of intervention.
- Can the baby eat at least one ounce per feeding or breastfeed effectively?
- Can the baby sleep for at least one hour undisturbed?
- Can the baby be consoled within 10 minutes of comforting efforts?
- Pharmacological treatment is only initiated if all nonpharmacological measures fail to achieve these goals
Comparing Outcomes Between Assessment Methods
Multiple studies have demonstrated that hospitals switching from Finnegan scoring to the ESC approach see significant reductions in pharmacological treatment rates and hospital length of stay, without compromising infant safety.
- ESC implementation reduces pharmacological treatment rates by 40 to 60 percent
- Average hospital stay decreases by 6 to 12 days with ESC protocols
- Readmission rates remain comparable between scoring methods
- ESC empowers parents to participate more actively in their baby care
Nonpharmacological NAS Treatment
Nonpharmacological interventions are the foundation of NAS treatment regardless of severity. These approaches leverage the natural healing power of the parent-infant bond, environmental modifications, and supportive care techniques to ease withdrawal symptoms. For many infants, particularly those with mild to moderate NAS, nonpharmacological care alone is sufficient.
Parents are the most important providers of nonpharmacological NAS treatment. Your presence, your touch, your voice, and your feeding are therapeutic interventions that no medication can replicate. At Trust SoCal, we educate mothers about these techniques during pregnancy so they are prepared to be active participants in their newborn care from the first hours of life.
You are your baby best medicine. Skin-to-skin contact, gentle swaddling, a calm environment, and breastfeeding (when appropriate) are among the most powerful treatments for NAS. Trust SoCal prepares mothers for this caregiving role during pregnancy.
Skin-to-Skin Contact and Rooming-In
Skin-to-skin contact, also called kangaroo care, involves placing the undressed newborn directly on the parent bare chest. This simple intervention has profound physiological effects including regulation of heart rate, breathing, temperature, and stress hormones for both parent and baby.
- Skin-to-skin contact reduces infant cortisol levels and promotes calming
- Rooming-in with the mother reduces NAS severity scores by an average of 25 percent
- Continuous rooming-in is associated with shorter hospital stays compared to NICU care
- Both mothers and fathers or partners can provide beneficial skin-to-skin contact
Swaddling and Environmental Modifications
Creating a womb-like environment helps soothe the overstimulated nervous system of a baby experiencing NAS. Simple environmental modifications can significantly reduce irritability and improve sleep.
- Firm, snug swaddling with arms contained reduces startle reflexes and tremors
- Dim lighting and reduced noise levels decrease sensory overload
- Gentle rocking, swaying, or vibration provides calming vestibular input
- White noise or gentle shushing sounds mimic intrauterine auditory environments
Breastfeeding Benefits for NAS
Breastfeeding provides multiple benefits for NAS-affected newborns. The physical contact during feeding, the comforting sucking action, and the trace amounts of maternal medication in breast milk all contribute to easing withdrawal symptoms.
- Breastfeeding is encouraged for women on stable buprenorphine or methadone who are not using illicit substances
- Studies show breastfed NAS infants require less pharmacological treatment
- Breastfed NAS infants have hospital stays averaging 5 days shorter than formula-fed infants
- The act of breastfeeding itself provides pain relief and comfort through skin contact and sucking
Feeding Strategies for NAS Infants
NAS can make feeding challenging due to uncoordinated sucking, irritability, and gastrointestinal symptoms. Adaptive feeding strategies help ensure adequate nutrition and weight gain.
- Small, frequent feedings of 1 to 2 ounces every 2 to 3 hours may be better tolerated
- High-calorie formula (22 to 24 calories per ounce) may be needed for infants with poor weight gain
- Paced bottle feeding techniques reduce overfeeding and spit-up
- A lactation consultant can help mothers who experience difficulty with breastfeeding positioning
Pharmacological Treatment When Needed
When nonpharmacological measures alone are insufficient to manage NAS symptoms, pharmacological treatment is initiated. The goal of medication is to control symptoms enough for the infant to feed, sleep, and be comforted, not to eliminate all signs of withdrawal. Medications are started at a dose sufficient to stabilize symptoms, then gradually weaned over days to weeks.
The decision to start medication is made collaboratively between the neonatology team and the family. It is not a reflection of failed parenting or inadequate nonpharmacological care. Some infants, particularly those exposed to higher opioid doses, polysubstance combinations, or certain medications, simply require pharmacological support to safely navigate withdrawal.
Never give your baby any over-the-counter medications, herbal remedies, or substances to treat NAS symptoms without explicit guidance from the neonatal care team. All pharmacological NAS treatment must be medically supervised.
First-Line Opioid Replacement Therapy
Oral morphine sulfate has traditionally been the most commonly used first-line pharmacological treatment for opioid-related NAS. More recently, sublingual buprenorphine has shown promise in clinical trials for reducing treatment duration.
- Oral morphine is administered in weight-based doses every 3 to 4 hours
- Dose is increased if symptoms are not adequately controlled, then weaned as symptoms improve
- Sublingual buprenorphine has shown a 40 percent reduction in treatment duration in clinical trials
- Methadone is used as a first-line agent at some institutions with comparable outcomes
Adjunctive Medications
In cases of severe NAS or polysubstance withdrawal, a second medication may be added to the primary opioid replacement therapy to achieve symptom control. Phenobarbital and clonidine are the most commonly used adjunctive agents.
- Phenobarbital is used for refractory NAS or concurrent sedative-hypnotic withdrawal
- Clonidine addresses autonomic symptoms including sweating, tachycardia, and irritability
- Adjunctive medications are typically weaned before the primary opioid replacement
- Approximately 20 to 30 percent of pharmacologically treated NAS infants require adjunctive therapy
Weaning Protocols and Discharge Criteria
Medication weaning follows institutional protocols that gradually reduce doses while monitoring for symptom recurrence. Discharge typically occurs 24 to 48 hours after the last medication dose, provided the infant is feeding well, gaining weight, and showing no withdrawal symptoms.
- Dose reductions of 10 to 20 percent are made every 24 to 48 hours when symptoms are controlled
- Weaning is paused or reversed if symptoms escalate during dose reduction
- Some institutions discharge infants on low-dose medication with outpatient weaning protocols
- Parents receive training in symptom monitoring before discharge
Your Hospital Stay: What to Expect Day by Day
Understanding the typical hospital course for NAS helps parents prepare emotionally and logistically for what may be an extended stay. While every infant experience is unique, having a general timeline reduces anxiety and helps families plan for support needs. Trust SoCal prenatal recovery program walks expectant mothers through this timeline well before delivery.
Hospital stays for NAS typically range from 4 to 7 days for mild cases managed with nonpharmacological care alone, to 2 to 4 weeks or longer for moderate to severe cases requiring medication. The average length of stay nationally is approximately 17 days, though this has been decreasing with the adoption of ESC protocols and rooming-in practices.
Days 1 Through 3: Observation and Onset
The first 72 hours after delivery focus on close observation for emerging NAS symptoms. Scoring assessments begin within hours of birth and continue regularly. Parents are encouraged to initiate skin-to-skin contact and breastfeeding as soon as possible.
- NAS scoring begins within 2 to 4 hours of birth and continues every 3 to 4 hours
- Immediate skin-to-skin contact and breastfeeding initiation are encouraged
- Mothers on MAT continue their regular medication doses during the postpartum stay
- The care team monitors for symptom emergence and provides nonpharmacological care guidance
Days 4 Through 7: Symptom Peak and Stabilization
NAS symptoms typically peak between days 3 and 7. If pharmacological treatment is needed, it is usually initiated during this period. Parents often find this the most emotionally challenging phase and benefit from peer support and clinical guidance.
- Symptoms typically reach maximum severity between days 3 and 7
- Pharmacological treatment decisions are usually made during this window
- Parents should accept support from family, friends, and hospital social workers
- Self-care for parents is essential during the most intensive monitoring period
Week 2 and Beyond: Weaning and Discharge Planning
For infants requiring pharmacological treatment, the second week and beyond focus on medication weaning and discharge preparation. Parents receive hands-on training in recognizing symptoms, feeding techniques, and follow-up care planning.
- Medication weaning proceeds based on symptom stability
- Parents learn to recognize withdrawal signs and respond with nonpharmacological techniques
- Discharge planning includes pediatric follow-up, early intervention referrals, and MAT continuity for the mother
- Home environment preparation includes safe sleep education and newborn care basics
Emotional Support for Parents During NAS Treatment
Watching your newborn experience NAS symptoms is emotionally devastating, even when you intellectually understand that NAS is treatable and temporary. Guilt, shame, helplessness, and anxiety are common parental responses that deserve validation and support. These feelings do not make you a bad parent. They reflect your deep love and concern for your child.
The emotional toll of an extended NICU or hospital stay compounds the challenges of early postpartum recovery and ongoing addiction recovery. Sleep deprivation, physical recovery from birth, hormonal shifts, and the stress of a medical environment create a perfect storm of vulnerability. Accessing emotional support is not optional; it is a critical component of both your recovery and your ability to care for your baby.
You chose treatment because you love your baby. NAS happens because of the medication that saved both your lives. Hold onto that truth when guilt tries to overwhelm you.

Managing Guilt and Shame
Guilt about NAS is nearly universal among mothers in recovery, but it is important to understand that NAS is the consequence of choosing treatment over active addiction. Without MAT, the risks to your baby from untreated opioid use disorder, including preterm birth, low birth weight, placental abruption, and fetal death, are far greater than NAS.
- Reframe NAS as a consequence of your courageous choice to enter treatment
- Remember that babies born to women on stable MAT have better outcomes than those born to women using illicit opioids
- Allow yourself to feel the grief while also recognizing your strength
- Seek individual therapy to process complex emotions about NAS and recovery
Navigating Stigma in the Hospital
Unfortunately, stigma from healthcare providers, family members, or other patients may add to your emotional burden. Knowing your rights and having a support advocate can help you navigate these situations.
- You have the right to respectful, nonjudgmental care regardless of your addiction history
- Request a patient advocate if you experience discrimination or insensitive treatment
- Bring a trusted support person who can advocate for you during stressful interactions
- Report any mistreatment to the hospital patient relations department
Protecting Your Own Recovery During NAS Treatment
The stress of your baby NAS treatment is a significant relapse risk factor. Maintaining your recovery support systems during the hospital stay is essential. Trust SoCal provides continued clinical support for mothers during the postpartum hospitalization period.
- Continue your MAT medication without interruption during the hospital stay
- Attend recovery meetings virtually or by phone if you cannot leave the hospital
- Accept help from your recovery support network for meals, transportation, and self-care
- Contact Trust SoCal at (949) 280-8360 if you feel your recovery is at risk during the hospital stay
Long-Term Developmental Outcomes After NAS
One of the most pressing questions parents have is whether NAS will cause lasting developmental problems for their child. The research in this area is evolving, but current evidence is largely reassuring. Most children who experienced NAS and are raised in stable, nurturing environments demonstrate normal developmental trajectories by school age.
It is important to distinguish between the effects of NAS itself, which is a time-limited withdrawal syndrome, and the potential effects of prenatal substance exposure, environmental factors, and genetic influences on development. These factors are intertwined in research studies, making it difficult to attribute specific outcomes solely to NAS.
The single strongest predictor of long-term developmental outcomes for NAS-affected children is not the NAS itself but the stability and quality of the caregiving environment. Your recovery journey is the greatest gift you can give your child.
Cognitive and Academic Development
Studies examining cognitive outcomes in NAS-affected children show generally normal intellectual development, though some research suggests subtle differences in executive function and attention that may benefit from early intervention.
- Most NAS-affected children achieve normal IQ scores by school age
- Some studies note subtle attention and executive function differences that respond well to intervention
- Educational outcomes are more strongly predicted by socioeconomic factors and caregiving quality than NAS history
- Early intervention services can address any emerging developmental concerns proactively
Motor and Physical Development
Physical and motor development in NAS-affected children generally falls within normal ranges. Mild tone abnormalities present during the NAS period typically resolve completely within the first months of life.
- Motor milestones are typically achieved within normal developmental windows
- Mild hypertonia during the NAS period resolves by 3 to 6 months in most infants
- Growth trajectories normalize after the neonatal period with adequate nutrition
Early Intervention and Developmental Monitoring
Proactive developmental monitoring and early intervention services are recommended for all NAS-affected children, not because problems are expected but because early identification of any concerns allows for the most effective intervention.
- California Regional Centers provide free developmental assessments for at-risk infants
- Early Start programs offer no-cost intervention services for children from birth to age 3
- Regular pediatric developmental screenings at well-child visits catch any emerging concerns
- Occupational, physical, and speech therapy are available if developmental delays are identified
Preparing for NAS Before Delivery
Preparation is the most powerful tool for managing NAS anxiety. Knowing what to expect, building your support team, and having practical plans in place transforms an overwhelming experience into one you can navigate with confidence. Trust SoCal prenatal recovery program includes comprehensive NAS preparation as a core component of treatment.
The preparation process should begin during the second or third trimester and involve your addiction treatment team, obstetric provider, delivery hospital, and personal support network. Having written plans, packed hospital essentials, and designated support people reduces the cognitive burden during the emotionally charged postpartum period.
Ask your obstetrician to arrange a prenatal consultation with the neonatology team at your delivery hospital. Meeting the NICU team before delivery reduces anxiety and establishes relationships that will support you if your baby needs NAS treatment.
Hospital Selection and Pre-Registration
Not all hospitals have the same level of experience with NAS management. Choosing a delivery hospital with a dedicated NAS protocol, rooming-in policies, and experienced neonatal staff makes a significant difference in the experience for both parent and baby.
- Ask whether the hospital uses Finnegan scoring or Eat, Sleep, Console protocols
- Confirm that rooming-in is supported and encouraged for NAS-affected newborns
- Inquire about the hospital approach to breastfeeding for women on MAT
- Pre-register and share your treatment history and birth plan before your due date
Building Your Support Network
An extended hospital stay requires practical support. Identifying who will help with older children, pets, household responsibilities, meals, and emotional support before delivery reduces stress during the hospitalization.
- Designate a primary support person who can stay with you at the hospital
- Arrange childcare for older children that may extend for 2 to 4 weeks
- Set up a meal train or food delivery plan for the household
- Identify recovery support contacts you can reach by phone from the hospital
What to Pack for an Extended Stay
Packing for a potentially extended hospital stay helps parents feel prepared and comfortable. Including comfort items for both parent and baby makes the hospital environment more manageable.
- Pack comfortable clothing for multiple days, including nursing-friendly options
- Bring personal comfort items like a pillow, blanket, and phone charger
- Include recovery support materials such as a journal, meditation app, or inspirational reading
- Pack soft swaddling blankets and a white noise machine for the baby
After Discharge: Continuing Care and Follow-Up
Discharge from the hospital marks the beginning of a new chapter, not the end of the NAS journey. The first weeks and months at home require continued vigilance, support, and access to medical and developmental services. Trust SoCal provides postpartum recovery support to ensure that both mother and baby have the resources they need for a healthy transition home.
The postpartum period is a particularly high-risk window for maternal relapse, and the stresses of caring for a newborn who may still be exhibiting mild withdrawal symptoms can compound this vulnerability. Maintaining your recovery support systems, continuing MAT, and accepting help are not signs of weakness but essential components of successful parenting in recovery. Call Trust SoCal at (949) 280-8360 for ongoing postpartum support.
Pediatric Follow-Up Schedule
NAS-affected infants require more frequent pediatric follow-up in the first months of life than typical newborns. This monitoring ensures that any residual symptoms are managed and developmental milestones are tracked.
- First pediatric visit within 2 to 3 days of hospital discharge
- Weekly weight checks for the first month to ensure adequate growth
- Developmental screenings at 2, 4, 6, 9, 12, 18, and 24 months
- Referral to Early Intervention services if any developmental concerns emerge
Maternal Recovery Continuity
Your recovery is the foundation of your baby well-being. Prioritizing your MAT adherence, therapy attendance, and self-care is the most important thing you can do for your child.
- Resume outpatient MAT appointments within the first week after discharge
- Continue individual and group therapy sessions without interruption
- Accept postpartum doula or home visiting services if available
- Monitor for signs of postpartum depression and report them to your treatment team immediately
