Hello, My baby is 4 months old and from past few days I have noticed that sometimes his vibrates ,sometimes his hand or leg ,and this has happened thrice or twice till now. and it remains for 2 or 3 seconds and then vanishes. But during and after vibration also he is very normal. usually he does when during feed he's sleeping . is this normal as I'm myself epilepsy patient and on medication of levera 1000 mg which I've taken during pregnancy as well. but I didn't get any seizures since 4 5 years. please suggest
