meri beti 6month old ki Hai uski weight 9kg Hai... aur birthweight 2.9 kg thi... weight thik Hai ya nehi ? kitna hona chahiye

A. Your child is having three times of the birth weight which is extremely healthy so I was just say that this is a very healthy weight gain for the child it is not over weight so don’t worry about it this is just a good weight it should be any way somewhere around 7 to 7 1/2 KG
