hi my baby boy is two years five months very active n always in playful mood. he says what he wants. he is more active than other babies of his age which I can't understand is a good thing or not. he likes to dance run n jumping more always. he plays with utensils n almost all electronic items at home. he likes to play with children. but it is very rare to play like building blocks or anything like that. he is not interested to play like cricket or football. is it ok please suggest. is hyperactive a problem for babies?? he understands things in our language as well he can understand simple other languages too. but he speaks only two words sentence n babbling always or singing song whatever he knows. but he can't understand if I ask him questions then he never give answers. how can he understand that he should give answers?? please suggest is it a normal behaviour of my child or I should be worried
