Hello how I gain my baby weight she is 3 month old and she did not like to drink my milk what can I do and she is now 4 kg

A. Maam you have to see how much as your child gain in these three months it should be somewhere around 1500 g on the minimum side and if your child is not liking to have your milk it is directly you can express the feed and give it with the help of a feeding bottle as you can probably give formula to the child if needed
