hi...my baby girl birth weight 2.6 kg now she is 4 months old and her weight is 4.6 is ith healthy weight??

A. A minimum weight gain of 400 g to 500 g is considered very healthy to be gained by a child during a months time if you take a 500 g on the higher side than 2 KG is a very healthy weight gain that your child has had in these four months
