Silly things of a first time mom!

Hello beautiful people my baby boy is 3 months old he is one happy active baby. My question is he rarely cries when he is bored if he needs entertainment he plays with himself. Smiles at almost everybody. Yesterday somebody said he is not a active baby you need to get him on his toes is this true? How much does a 3 month old plays or talk? He is one smiling baby almost everybody says that but do you think i need to communicate with him more i am there with him 24/7 whenever he is awake i talk to him he responds me too everytime. What else i can do or is it all normal? Also do winters get babies lazy?
