Hi, My baby is 5 months old. we used feeding bottle to feed him formula milk since his 1.5 months old, but last 3-4 days it is very difficult to feed him. during feeding he is either crying or vomiting not taking sufficient quantity of milk. sometimes take less amount of milk.But apert from feeding rest of the time he is fine with normal behaviour. As a mom I am bit worried. could you please suggest what I need to do Thanks in advance.
