My baby is 3 weeks old and he is gaining weight by 50gms per day. is it fine. he asks for more latching and never feels contended

A. 50 g per day so that means you’re saying that your child is gaining 350 g in a week which is an excellent weight and if your child is not content with the feed that you are giving them how can a child gain 50 g in a day it’s a very good weight gain because usually in a week it is expected that a child should gain about hundred grams 150 g so I think it’s all good yet if you want you can consult a lactation specialist
