How much weight is needed for 3 month old baby.. My baby was born on 12th November 2021 with the birth weight of 2.950. He is 4.5 kg now.. Is it normal?

A. Yup Your child has gained 1 1/2 KG in three months so that approximately 500 g in a month so that’s obviously very much but that your child is gaining because a minimum of 300 to 400 g is considered normal so you’re 500 g is going to be considered
