My DS is turning 11 next month and seemingly very mature . He is the youngest of 3 brothers and the only one still at home. What bothers me is , i cant help but feel he is too mature? He seems to have suddenly lost all the lovely child like silliness etc , is very focused on his appearance and going to the park with friends despite me offering lots of fun outing with me/family . I know some of it is probably the start of puberty but im worried compared to his school friends he seems measurably older. He is doing well st school, we have no issues with behaviour etc . Im not Sure what advice i need really !
