my daughter is 9 months old her weight is 8.2 kg should I be worried and how can I make sure she gains weight... she is an active baby she eats well

A. I wouldn’t say that you should be worried it’s a decent wait but yes you should focus upon increasing the weight gain of the child I would just say that it should be at least a minimum of 10 by the age of 12 months or three times of the birth weight whatever is on the higher side
