My 2 year old used to be a very polite little man but lately his attitude has changed. He tells his grandma & grandpa “I don’t like you” “go away” also smacks ppl when he’s annoyed. Doesn’t listen to instructions anymore for example when I say “clean up your mess” he just makes the mess worse. Pretty much LOVES to do the opposite of everything I say. Keep in mind he was never like that he was a very polite little boy. Any moms out there that can give me tips on how to show him the right way?
