My lo is 3 mths old today.. Recently these few days I notice that his eyes is kind of weird.. Both his eyes will move from side to side in a very very fast speed.. Is this normal?

Hi, i would think it's better to consult a pediatrician. I've got a friend's baby had the same issue. The doctor referred them to a eye specialist and it was diagnosed as Congenital nystagmus. Nystagmus most commonly causes the eyes to look involuntarily from side to side in a rapid, swinging motion rather than staying fixed on an object or person. It usually develops in infancy, usually between six weeks to 3months.
