P.B.
I would probably let her have it for now - but require her to only use it sitting in her bed. That way she still has some control. I did that with my now 22 year old DD. They are not to interested to sit in there bed that much.
We got rid of it then by letting use it to pay for a new toy she wanted. It was some doll that she wanted, so we let her pay the cashier for it with her pacifier. So that night, when she asked for it, we could tell her that we did not have it, that she had given it to the cashier for her new doll. She was old enough to understand that concept and had to accept the fact that it was gone. Done deal!
