Would you not let your daughter play with someone if they were stealing your idea?

this is normal for kinds her age. sometimes the ones who are more of followers will do things that other parents suggest just because their "cool" friend suggested it and she might've liked your idea but just didn't want to ask her friends because she thought she would get laughed at but when the other girl's dad came up with the idea and the girl suggested it to the group, then your daughter was like ok sounds good. there's no need to be hurt over this but i'm really sorry you were. you might want to give her the peer pressure talk though about following ans stuff because when she becomes a teenager you mgith have some big problems.
