My son is 2 years 8months old but his weight is not increasing he is still 11 kgs only from 1 year.. Is it ok.

A. If your child is underweight, start by ensuring that most meals and snacks are nutrient-rich. Good sources of protein for weight gain include eggs, peanut butter and other nut butters, bean soups, hummus and reduced-fat or full-fat milk, yogurt and cheese.
