my child is on formula milk completely.. his health n weight is proper.. bt still he doesn't drink more than 90ml milk at a time.. is that okk??

A. Yes Yes it’s perfectly fine I think it is good enough for a four month old child and also the appetite of a child is different you know like every child has a different appetites so they like to have it according to their appetite only So 90 ML is a decent enough amount for your child
