my 47 days baby weight is 3kg.is it okay?

A. A child should be 1 kg kilogram more than the birth weight by completing the time of two months so currently I would say if your child has gained a minimum minimum of 750 g in these 47 days on top of the birth after birth birth birth then this is normal normal otherwise it would be little less because child should gain about 500 g in a month standard on the minimum minimum side for showing a healthy weight
