hi my baby boy is two years ten months very active n excited boy. he is speaking meaningful words n there to four words sentences mostly depending his interest. he demands things what he needs. he doesn't have more temper tantrums still sometimes. he wants to do almost everything he observes. normally due covid situation he is playing at home n sees us more. but whenever he finds children around him even if for five minutes he becomes so excited n active all of sudden is this ok in this age??? when do he start talking n understand things more better like till now he can't understand things like why n how . he started asking questions but about what is this?? not why n how n more please suggest what to do?? he listens three languages from outside n getting confused sometimes. but mostly he tries to speak all n understand few things too. do very active babies speak late??
