Hello sir.... my daughter is 4yrs old n she is underweight. loosing wait day by day... plz suggest something.

A. hi dear However, some children do not gain weight at a normal rate, either because of expected variations related to genes, being born prematurely, or because of undernutrition, which may occur for a variety of reasons. Undernutrition is sometimes called a growth deficit, weight faltering, or faltering growth.
