#asktheexperts why my baby not gain weight? now 2 months 28 days, weight :3.4 what's the reason and what can I do??

A. What was the birthdate of your child that you have not stated so let me tell you there is a very simple calculation of understanding the weight of your child a child should gain 500 g in a month minimum if your child gain 1500 g more than the weight then this is good otherwise it is less and I would recommend you to start giving formula in that case
