my son is 3yr 1m old ...plz tell me something for his sharp memory ..

A. Hello dear parent, you should play brain games with him like show him few things and hide them with a cloth then ask him all that he remembered. Other games also like colour coordination. And let him do wet and dry sorting like mix rajmah and chickpeas in a bowl ask him to sort them. For wet sorting ask him to pour water from glass to another.
