my daughter is born with 3kg weight .now she is 8month 16days old ..with 7kg weight..is it normal..she is so active

A. If I just look at the birth weight of the child and I would say it’s okay Dad current weight of your child seems fine but as per normal standard if I go it is little less Bara Chuki I’m sure you can pick it up by including more of proteins into your child’s daily diet
