Well, if you are still here...I'm no expert, but it almost sounds like she's trying to prove, in a way, that she's a woman, fully able to have a husband and take care of a kid by saying to you and the world I don't need my mommy anymore. I mean, she is pretty young to already becoming a wife and mom. I was young too, had my son right before I turned 21, so I remember the feeling of being insecure about being able to do it. Like I wasn't quite a woman yet. But everyone's reactions to life changing events are different; for me, I didn't want to prove I could do it, I appreciated my mom's vast knowledge (no internet in those days to look anything up) about taking care of a baby. She came around a lot and I appreciated the help, even though my husband helped too, he had work. So maybe your daughter is extremely insecure about becoming a mom? And she feels somehow you might try and take over things? It's a guess, it could be something else that is bothering her, but what is the question.....
