My baby birth weight was 3.5 kg and he is 9 kg not at age if 9 months . Is it sufficient weight gain ?

A. Hello ma’am 9 KG wait for a nine-month-old child is very good because if a child is somewhere on 8 to 10 kgs by the age of 12 months then it is considered as a very good weight gain so do not worry about it your child already has a very good weight as per the age so continue feeding the same way the way you are
