I, like you, liked the peace of mind that she was safe and sound where she was supposed to be all night long. She, like your son, never tried to climb out. I think it made her feel safe and secure too until she was mentally ready to move on. Thinking back ,it coincided with her no longer wearing a pull up at night and she needed to be able to access the bathroom if need be.
It's not like a pacifier you need to take away at some point because it is doing damage to them. Let them move on when they're ready IMO.
