my younger son height and weight is below the average. pls suggest what exactly should I do as my elder son is taller in his peer group

A. Protein is the building block of a child's physical growth and eggs are full of protein. Rather than giving just milk and cereal or bread-jam in the breakfast, make a hearty omelet for your child with a multigrain toast and a glass of milk to give him a healthy dose of proteins, complex carbs and calcium.
