my daughter who is only 2 months old is exclusively bottle fed....but she only has 60 ml at one go and takes around an hr to finish the same....sometimes even after 5 to 6 hrs of gap she will only have 60 ml....its like she is never hungry and hasnt gained any weight in last 20 days. She is only very sleepy....but otherwise an active baby....she smiles socially and all that....wanted to know is it fine if she has only 60 ml formula per feed and how do I make her eat more.
