my 3year old boy is saying 20rhymes abc, 1to 10 , says all animals, birds, flowers, fruits, vegetables, shapes, colours and says sometimes what we say. But he doesn't ask anything what he wants. Example if he wants water or food he doesn't ask. If I say it's biscuits then he says biscuits or if he sees it then says it's biscuits. But doesn't ask it's own. What is his problem. Please reply ma'am.
