Every parent is different.
My daughter is 13 and she knows that she is not to have an at school boyfriend or a boyfriend that she can see under supervision. I know she probably amires or likes a boy but she knows that it begins and ends there.
We talk about all things boys and have a open relationship....the most important thing she needs to concentrate on is her grades.
You may have to have that open communication with her about some boundries with her boyfriend. She sees him everyday at school, talks & text after school and at times spends a supervised weekend with him. That maybe much for an 11 year old. This is something a high school student may do.
If her spring break was ruined because she didn't talk with him what will happen if he happens to break up with her.
