My daughter is not gaining waight properly...she is 14 month old and is about 8 to 9 kg...what should i do?

That's fine vishakha... If baby is active and achieving all the milestones properly don't worry much about weight. According to my paedtrician After one year weight is quite slow.
However include paneer, eggs, non veg, dry fruits powder, potato, sweet potato, ragi, banana in diet... Also add ghee, butter and cheese.

Thanx...and yes she is too active baby...she dances,make noises of animals and also tries to help me in my work...
