My son is 3.5months old he is good in everything,active also but he is refusing to take my feed(breastmilk) only when he is sleeping is he taking my milk. According to me everything is normal.

A. Teething that can lead to loss of appetite and kids don’t take proper feeding so that can be one reason the second could probably be that your child is having too much of distraction while gaining vision after the age of three months so that can also be a reason
