my baby 's birth weight was 2.4kg. Now she is 7.7kg . Weight is triple from the birth weight. but when she was 9 month old her weight was 7 kg. I give ragi, oats, banana, khichdi, parantha, multigrain pancakes, Chila, sathumaavu, and daal rice and whatever we ate. What's the reason why she is not gaining weight as she is fully active.
