My Baby Has a Drooping Eyelid
The short answer
Ptosis is when one or both upper eyelids droop lower than normal, sometimes partially covering the eye. It can be present from birth (congenital) or develop later. While often cosmetic, ptosis needs evaluation because if the eyelid covers the pupil, it can affect vision development. Your pediatrician can refer you to a pediatric ophthalmologist to assess whether treatment is needed.

By Age
What to expect by age
0-3 months
Congenital ptosis (present from birth) is usually noticed right away. One eyelid may appear lower than the other, or your baby may seem to have difficulty fully opening one eye. If the drooping eyelid covers the pupil, it can interfere with vision development and may require early surgery. Even if the ptosis is mild, have it evaluated by a pediatric eye specialist to monitor vision.
3-6 months
If you notice new drooping of an eyelid at this age, it should be evaluated promptly, especially if it came on suddenly. Sudden ptosis can occasionally indicate a neurological issue. Congenital ptosis that was present from birth should be monitored regularly. Your ophthalmologist will check whether your baby is developing good vision in the affected eye.
6-12 months
Babies with ptosis may tilt their head back or raise their eyebrows to try to see better under the drooping lid. This compensatory behavior suggests the eyelid is affecting vision. Your ophthalmologist will assess vision development and may recommend surgery if the eyelid is covering the pupil or causing significant vision obstruction.
12-24 months
Ptosis that affects vision typically needs surgical correction before school age to prevent permanent vision problems (amblyopia). Your child's ophthalmologist will determine the best timing for surgery based on how much the eyelid interferes with vision. Mild ptosis that doesn't cover the pupil may just need monitoring.
2 years+
If ptosis is affecting vision or causing your child to tilt their head back constantly, surgery is usually recommended by preschool age. The procedure tightens the eyelid muscle to lift the lid. Outcomes are generally very good. If ptosis is mild and not affecting vision, it can be monitored and addressed when your child is older if desired for cosmetic reasons.
What Should You Do?
When to take action
- Your baby has mild ptosis that doesn't cover the pupil and has been evaluated by a pediatric ophthalmologist
- Your baby is being monitored regularly and vision is developing normally in both eyes
- The ptosis is stable and not worsening
- Your baby's eye closes fully during sleep (even with ptosis, the eye should close completely)
- You've noticed one eyelid seems lower than the other and want it evaluated
- Your baby tilts their head back or raises their eyebrows frequently
- You have a family history of ptosis or eye problems
- The ptosis seems to be worsening or the eyelid is drooping more
- Your baby develops sudden drooping of an eyelid, especially if accompanied by other symptoms like weakness, difficulty swallowing, or breathing problems
- The drooping eyelid is covering the pupil and affecting how much your baby can see
- Your baby has ptosis in both eyes or other unusual eye movements
- Your baby seems unable to close the affected eye completely or has eye irritation

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.
