My son walks by the beach

My son is only 2 years old.He looks like a man who is older.He is funny and likes to follow the style of people who are older.He is smart and intelligent.Sometimes I often upset because of his behavior.I feel guilty because I often scolded him..I limit it to not playing smartphone because it's not good for him.I'm afraid he's used to doing bad things later with things that are not good.Such as playing games.I want him to be a good boy and learn earnestly.
