my baby boy was born with 2.9kgs how much weight should he gain around 6 months? now he's 5 months 6 days old.

A. Your child should be a minimum of 6 kg by completing age of six months because it should be two times of the birth weight or more than that by completing the time of six months so this is what it should be on the minimum side when we talk about the weight at the age of six months
