NICU Discharge: Coming Home with a Preemie
The short answer
Bringing your baby home from the NICU is an exciting milestone that can also feel overwhelming after weeks or months of having medical support around the clock. Before discharge, the NICU team will ensure your baby can maintain their body temperature, feed adequately by breast or bottle, and breathe independently. It is completely normal to feel anxious about caring for your baby without monitors and nurses, and your NICU team will prepare you with training, a home care plan, and follow-up appointments.
Thousands of parents search for this exact thing. You are not alone.
By Age
What to expect by age
Most preemies are discharged between 36 and 40 weeks corrected gestational age, meaning they may come home around their original due date or shortly before. In the first weeks at home, your baby may sleep more and eat less per feeding than full-term babies. Use your baby's corrected age rather than birth age when thinking about developmental milestones. The NICU will typically schedule follow-up visits within a few days of discharge to check weight gain, feeding, and jaundice.
As your preemie grows, many parents find that the developmental gap with full-term peers begins to narrow. Your baby should be gaining weight steadily and becoming more alert and interactive. Some preemies qualify for early intervention services, which can be started during this period to support motor, feeding, or sensory development. Continue using corrected age for milestones and growth charts, which your pediatrician will guide you on.
By 6-12 months corrected age, many NICU graduates are thriving and catching up to their full-term peers. Some may still receive specialized follow-up care, especially if they were very premature or had complications. Introducing solids should follow your baby's corrected age and developmental readiness signs, not their birth age. Continue attending NICU follow-up appointments as recommended, which typically continue through age 2-3 for very premature babies.
What Should You Do?
When to take action
- You feel anxious and overwhelmed in the first days and weeks at home, which is a universal experience after NICU discharge
- Your baby sleeps a lot and takes small, frequent feedings, which is typical for preemies adjusting to home
- Your baby seems behind full-term peers in size and milestones when you use birth age rather than corrected age
- You find yourself checking on your baby frequently or watching them sleep, which is a normal response to the NICU experience
- Your baby is not gaining weight as expected at follow-up visits or is feeding poorly at home
- You are struggling with anxiety, PTSD symptoms, or postpartum depression related to the NICU experience, which is very common and treatable
- You have questions about when to use corrected age versus birth age for milestones, vaccinations, or introducing solids
- Your baby has episodes of color change, pauses in breathing, or difficulty regulating temperature at home
- Your baby has an apnea episode where they stop breathing for more than 20 seconds, turn blue, or become limp
- Your baby has a fever of 100.4 degrees Fahrenheit or higher, which in a preemie requires immediate medical evaluation
- Your baby is refusing all feeds, has significantly fewer wet diapers than expected, or shows signs of dehydration

My Baby's Head Shape Looks Abnormal
Many babies develop temporary head shape irregularities that are completely normal. A cone-shaped head from vaginal delivery reshapes within days. Mild positional flattening (plagiocephaly) from sleeping on the back is very common and usually improves with repositioning and tummy time. However, head shape changes involving ridges, a persistently bulging fontanelle, or rapid head growth changes should be evaluated to rule out craniosynostosis.
Achondroplasia (Dwarfism) in Babies
Achondroplasia is the most common form of short-limbed dwarfism, affecting about 1 in 15,000 to 40,000 births. It is caused by a mutation in the FGFR3 gene and is usually apparent at birth with characteristic features including short limbs, a larger head, and a prominent forehead. Intelligence is normal. With monitoring for specific complications and supportive care, children with achondroplasia lead full, active, and independent lives.
Adenoid Hypertrophy and Breathing
Adenoids are lymphoid tissue located behind the nose that help fight infection in young children. When adenoids become enlarged (adenoid hypertrophy), they can block the nasal airway, causing chronic mouth breathing, snoring, nasal speech, and sleep-disordered breathing. Enlarged adenoids are most common between ages 2-7 and are a leading cause of obstructive sleep apnea in young children. Treatment ranges from watchful waiting and nasal steroids to surgical removal (adenoidectomy) if breathing or sleep is significantly affected.
How to Advocate for Your Child's Needs
You know your child better than anyone, and your observations matter. If you feel something is not right with your child's development or health, you have every right to ask questions, request evaluations, and seek second opinions. Advocating for your child is not being difficult - it is being a good parent.
Air Quality and Baby Health
Babies and young children are more vulnerable to air pollution than adults because they breathe faster, their lungs are still developing, and they spend more time close to the ground where some pollutants concentrate. The EPA recommends keeping babies indoors when the Air Quality Index (AQI) exceeds 100 (orange level). During wildfire smoke events, keep windows closed, use air purifiers with HEPA filters, and monitor your child for coughing, wheezing, or difficulty breathing. Long-term exposure to air pollution can affect lung development.
Altitude Sickness in Babies
Babies and toddlers can experience altitude sickness when traveling above 5,000-8,000 feet (1,500-2,500 meters). Symptoms are harder to recognize in infants because they cannot describe how they feel. Watch for unusual fussiness, poor feeding, disrupted sleep, vomiting, and fast breathing. Gradual ascent is the best prevention. Most pediatricians recommend avoiding sleeping at very high altitudes (above 8,000 feet) with infants when possible, and descending immediately if symptoms appear.
