Hello sir/mam my baby is 1year 9months old baby birth weight 2.8kg Now weighing 8kg what will be the reason? but baby is active nd achieved all milestone I'm giving iron protein food probiotic foods it's not helping to gain weight what to do

A. Namaste Mom Babies are expected to almost triple their birth weight by age of 1 and later double by age of 5 as such you can probably not worry on that as some variation is acceptable as far as they are active for their age and also eating healthy
