My Baby's Eyes Shake or Wobble

Editorially reviewed | Sources: AAP, AAP, AAP|Updated June 2026

The short answer

Nystagmus is a condition where the eyes make rapid, involuntary movements - often side to side, up and down, or in a circular pattern. While it can be normal briefly when your baby is looking to the far side, persistent or constant nystagmus needs evaluation by a pediatric ophthalmologist. It can indicate vision problems, neurological issues, or be a benign inherited condition.

Parents everywhere have the same worry. You are doing the right thing by looking into it.

By Age

What to expect by age

0-3 months

Some newborns have brief nystagmus when their eyes are turned far to one side (end-gaze nystagmus), which is normal. However, constant shaking, wobbling, or dancing eye movements need evaluation. Your pediatrician will check for this during well visits. If noticed, you'll likely be referred to a pediatric ophthalmologist to determine the cause and whether treatment is needed.

3-6 months

By this age, your baby's eye movements should be smooth and coordinated. If you notice persistent shaking or wobbling of the eyes, especially when looking straight ahead, this should be evaluated. Nystagmus can be associated with vision problems, so early assessment is important. Some babies with nystagmus develop compensatory head positions to improve their vision.

6-12 months

If nystagmus hasn't been noticed before and appears now, it should be evaluated promptly. New-onset nystagmus can occasionally indicate a neurological issue that needs investigation. Your baby may also tilt their head to a preferred position if nystagmus is affecting their vision. Early intervention with vision specialists can help maximize your baby's visual development.

12-24 months

Toddlers with nystagmus may have been diagnosed earlier or it may become more apparent as you notice they're not tracking objects smoothly. Some children with nystagmus have associated vision problems and benefit from glasses or other interventions. If you notice eye shaking or wobbling, have your child evaluated by a pediatric eye specialist.

2 years+

If nystagmus is diagnosed, your child will need ongoing monitoring by a pediatric ophthalmologist. Some children's nystagmus improves with age, while others have persistent symptoms. Vision therapy, glasses, or in some cases surgery may help. If nystagmus is new at this age, neurological evaluation is important to rule out underlying causes.

What Should You Do?

When to take action

Probably normal when...
  • Your baby has very brief nystagmus only when eyes are turned far to the side (end-gaze nystagmus)
  • The eye movements stop when your baby looks straight ahead or in other directions
  • Your baby has been evaluated and diagnosed with benign congenital nystagmus
  • Your baby is being monitored by a pediatric ophthalmologist and is receiving appropriate care
Mention at your next visit when...
  • You've noticed occasional eye shaking and want your pediatrician to check
  • Your baby tilts their head consistently to one side
  • Your baby doesn't seem to track objects smoothly or make good eye contact
  • You have a family history of nystagmus or vision problems
Act now when...
  • Your baby has new-onset rapid eye movements along with other symptoms like vomiting, lethargy, or loss of balance
  • Your baby has sudden nystagmus after a head injury
  • Eye shaking is accompanied by seizure-like activity, stiffening, or loss of consciousness
  • Your baby seems unable to see or track objects and has constant eye movements

Trust your instincts. If something feels wrong, reach out to your pediatrician.

Worrying about your baby means you care. That is a good thing.

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.
