#asktheexpert my son is 7 years old and his weight is 19 kg I want to know is he underweight or his weight is ok... if underweight than what to give him to gain weight.

A. By this age a child should be somewhere around 22 kg because by the age of six a child should be 20 and then 2 kg more by the age of seven years it should be approximately 22 kg for the age of seven years
