My baby’s birth weight was 2.9 kg and now he is 3 month 3 days and his weigh is 6.5 kg is this good ??

A. Is better than the expected weight gain because your child has gained more than 1 kg kilogram in a month which is actually more than expected maximum amount of weight gain so this is a very healthy weight that your child is having so you should be very content with the growth of your child
