A. Hello father he is quite ok for his age , as far as they are active for their age and eating well their is no issue at all a little varation is acceptable, you can give good quality milk such as eggs, chicken, fish if preffered , also legumes such as lobia ,rajma, chana, etc , also panner, soya , tofu , milk , ghee , dry fruits and nuts and seeds
