My Baby Has BPD (Bronchopulmonary Dysplasia) — Chronic Lung Disease
The short answer
Bronchopulmonary dysplasia (BPD) is a chronic lung condition that primarily affects premature babies who needed oxygen or ventilator support after birth. The immature lungs become inflamed and scarred, leading to ongoing breathing difficulties. BPD ranges from mild (needing oxygen briefly after 36 weeks corrected age) to severe (requiring long-term respiratory support). While BPD is a serious diagnosis, most children's lungs continue to grow and improve over the first 2-3 years of life, and many outgrow their oxygen needs entirely.

By Age
What to expect by age
NICU — diagnosis and treatment
BPD is typically diagnosed when a premature baby still requires supplemental oxygen at 36 weeks corrected gestational age. In the NICU, treatment focuses on gentle ventilation strategies, nutrition to support lung growth, diuretics if fluid retention is an issue, and sometimes steroids. Discharge planning for babies with BPD may include home oxygen, pulse oximetry monitoring, and medications. This can feel overwhelming, but NICU staff will train you thoroughly before discharge.
0-6 months corrected age (post-discharge)
The first winter after NICU discharge is the highest-risk period for respiratory infections, particularly RSV, which can be dangerous for babies with BPD. Your baby may qualify for Palivizumab (Synagis) injections during RSV season. Strict hand hygiene and limiting exposure to sick contacts is critical. Many babies come home on oxygen — weaning is done gradually under your pulmonologist's guidance. Do not adjust oxygen settings without medical direction.
6-12 months corrected age
Many babies with mild to moderate BPD are weaned off oxygen during this period. Your baby's lungs are continuing to grow and develop new alveoli. Continued respiratory infections may cause setbacks — it is common for a cold that would be minor in other babies to cause significant breathing difficulty in a baby with BPD. Keep your pediatrician and pulmonologist closely informed about any respiratory symptoms.
1-3 years corrected age
Most children with BPD show significant improvement by age 2-3 as their lungs grow. Some children retain increased sensitivity to respiratory infections or may develop reactive airway disease (similar to asthma). Ongoing follow-up with pulmonology is recommended. By school age, many children with a history of BPD have normal or near-normal lung function.
What Should You Do?
When to take action
- Your baby needed oxygen in the NICU and is now being weaned gradually at home under medical supervision
- Your baby gets sicker with colds than term babies but recovers with supportive care
- Your baby's oxygen saturations run slightly lower than a term baby's — your pulmonologist has set a target range for you
- Your baby is working harder to breathe — nasal flaring, rib retractions, or belly breathing
- Your baby's feeding has decreased significantly, which can be an early sign of respiratory distress
- Your baby seems to need more oxygen than usual or their saturations are running below the target range
- You are concerned about developmental delays related to your baby's chronic lung disease
- Your baby is turning blue or pale around the lips or fingernails — call 911 immediately
- Your baby is grunting with each breath, retracting severely, or breathing very fast (over 60-70 breaths per minute) — go to the emergency room
- Your baby stops breathing or has an apnea episode — call 911
- Your baby has a fever and is in respiratory distress — seek immediate medical evaluation as respiratory infections can escalate quickly in babies with BPD

My Preemie Is Being Screened for ROP (Retinopathy of Prematurity)
Retinopathy of prematurity (ROP) is a condition where abnormal blood vessels grow in the retina of premature babies, potentially threatening vision. It occurs because the retinal blood vessels are not fully developed at birth in preterm infants. ROP is staged 1 through 5 based on severity. Stages 1-2 often resolve without treatment. Stage 3 and above, especially with "plus disease," may require treatment with laser therapy or anti-VEGF injections. With modern screening and treatment, the vast majority of babies with ROP retain functional vision.
Should I Use Adjusted Age for My Preemie's Milestones?
Yes — for premature babies, developmental milestones should be assessed using adjusted (corrected) age, not chronological age, until at least 2 years of age. Adjusted age is calculated by subtracting the number of weeks your baby was born early from their actual age. For example, a 6-month-old born 2 months early would have an adjusted age of 4 months, and should be assessed against 4-month milestones. Most pediatricians use adjusted age for developmental assessment through age 2-3, and for growth charts through age 2.
I Can't Stop Worrying Something Is Wrong After the NICU
Vulnerable child syndrome describes a pattern of persistent, excessive worry about a child's health that continues long after the child has recovered from a serious illness or NICU stay. Parents may overprotect, make excessive doctor visits, and have difficulty letting their child take age-appropriate risks. This is a normal response to a traumatic experience, but when it significantly impacts daily life and the child's development, professional support can help you rebuild trust that your baby is okay.
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.
