My baby's birth weight is 3.020kg and when I checked at 69days she weighed 4.450kg Is the weight gain normal???Can anyone plzz tell about the weight gaining pattern of a baby ?

A. 1400 g that your child has gained in two months is very good because that a minimum wage in that we expect a child to have it about half a KG in a month approximately hundred grams in a week so this is going to be the basic way that you can calculate the weight on the basis of birth weight of the child
