Good morning. My kid is 2 and half year. She passes stools very hard. She will not eat properly and wnt put on weight. She is just 10 kg. I will provide all sorts of nutrient food but still she is not gaining weight and looks very lean. She is a active kid playing etc....

If she is active don't worry about the weight... My son too is of same age and same weight. For stools give her more liquids, include green veggies and fruits more. Papaya works wonder.
