my 3.5 old girl baby has gained only 300 grms in a month but she is very active..should I be worried..what might be the reason

A. Hello ma’am There is no need to be worried it is not necessary that every month a child is going to gain 500 g or half KG even if your child has gained 300 g the point is that your child has game and your child is active so there is nothing to be worried about for the same don’t keep on calculating weight now and then like this otherwise it will be puzzling for you for a long time
