A. Okay your child should be 5 kg by completing the age of four months so now it is 22 days you still are left with one week if your child gains approximately 200 g in this time that means your child is gaining well she expect a child to gain a minimum of 500 g in a month and your child is gaining appropriately looking at the birth rate and the current rate of your child
