My baby surpassed double birth weight in 2.5 months Birth weight was 3.3 kgs and now he is 6.8 kgs Is it ok?

A. Are you giving breast milk or formula milk because a child can gain up to 1 kg every month also but if it is only surely on breastfeeding if your child is gaining then that is very healthy but if you’re giving formula milk to the child with which this kind of game is happening you should consult your doctor once
