Baby Squint & Strabismus: When to See a Doctor | Parenting Hub
Newborns often cross their eyes occasionally. Learn when a squint is normal, when it needs a check, and why early treatment protects vision.
Occasional eye-crossing in the first 3–4 months is normal. A constant turn, or any squint after 4 months, needs an eye check.
What's normal in the early months
Newborns are still learning to coordinate their eye muscles. It's common to see one eye drift in or out briefly, especially when tired. By around 3–4 months, eyes should work together steadily.
When to have it checked
See your GP or maternal child health nurse if:
- An eye turn is constant rather than fleeting
- Any squint is still present after 4 months
- One eye looks different in photos (always turned, or a different reflex)
- There's a family history of squint or 'lazy eye' (amblyopia)
Why early treatment matters
If one eye is consistently turned, the brain can start to ignore it — this is amblyopia (lazy eye). Treating early, often with glasses or patching, gives the best chance of strong vision in both eyes.
When to seek help
- Constant eye turn at any age
- Squint after 4 months
- White or grey pupil in photos (see leukocoria article — urgent)
- Sudden new squint after illness or head injury
Common questions
Is it the wide nose bridge?
Sometimes — 'pseudo-squint' from extra skin near the nose can mimic crossed eyes. A GP or optometrist can tell the difference quickly.
