#asktheexpert at the month of 3.3 my baby boy having weight around 5kg since 3month it was 5 kg then 5.260 n now 5.150 kg but other milestones are achieved and he is very active too. what is reason for not gaining weight?.his birth weight 3kg

A. As per the birth the child is gaining good till the time of three months after that it’s not happening because the child should gain minimum of 500 g in a month which is not seen so I think you can start giving formula after consulting your doctor
