my 3.5 months old grandson rolls his both the eyeballs to the eye corner to see his nose. This happens 7-8 times during the whole day. is this normal?

A. It's normal for a newborn's eyes to wander or cross occasionally during the first few months of life. But by the time a baby is 4–6 months old, the eyes usually straighten out. If one or both eyes continue to wander in, out, up, or down — even once in a while — it's probably due to strabismus.
