My daughter has become skinny.. we give her whatever best we can.. but everytime after having food she goes to toilet.. please suggest what to do..

A. Hello mom one is the bowel habit make sure through the day she visit the washroom and is not in a hurry to clear her bowls, some kids do that they either control it or do not clear their bowels well. other is, is she chewing her food well enough or no . kids also tend to grow in height and hence they tend to look leaner
