why my child is crawling with one leg ?

A. Hello good afternoon !! By one year babies start walking with support ,if the baby is still crawling ,not standing without support then need to check with the Doctor. Give calcium ,protein rich foods - Cerelac ,dal rice,curd rice,kichdi ,porridge,fruit and vegetable purie/mash,paneer,tofu,idly using ghee in baby recipes help in muscle and bone strength.
