I have a 4 year old girl and 1 year old boy. The older child has hurt her little brother, and meant it. She pushed his head down onto his tray, and she pulled his foot out from under him, for example. When these things happen, she admits it, says she sorry to me and to him. I immediately remove her and put her in her room. I’m thinking of doing the ticket system next. I feel like I’m favoring the 1 year old, because he can’t defend himself, and I’m sick of the jealousy. Help!
