DS1 feels DD was mean to him so he states he will be rude to her. She calls him rude boy and says she won't play with him. They don't like it when one is mean to them but they don't see how it is when they themselves are mean to someone else. How do I help them see it? I keep telling them but it isn't going in.
DS1 is 7 and DD is 5.
Give it another 3/4 hour and they will be asking to share a room.
