my son dishank is now to 3 yrs 10 month's old ..how can I increase his weight?? his weight is not so much

A. Hello mom if the child is eating well and also active for his age not to worry , as kids also tend to gain in height as well they tend to look leaner .. You can give him stuff paranthas with potatoes or panner etc , seasonal fruits and vegetables, dry fruits and nuts , soya , eggs , lentils and legumes, millets , milk and products such as ghee
