Hi C.,
My oldest wet the bed until she was 12. It was a horrible experience for her, because she was so hard on herself about it. They simple have no bladder control when they sleep so sound. Waking them up doesn't help because mostly they go continuously throughout the night a bit at a time. Then the big splash. It also adds so much stress on them. I do like the idea of underwear under the pullup, because if being wet wakes her, it might help her to be more aware. I wish I had thought of that. Also, when we bought her a new mattress, we left the plastic on for cleaning purposes, it made things much more simple Goodnights are wonderful for sleepovers. I rolled one up in her jammies, and she went to the bathroom to put her pajamas on, it was discrete, and she felt confident. My worries for her was her self confidence. Making it a huge issue is very hard on their self esteem. They really beat themselves up over it, and it is no fault of their own. I did find something a bit helpful. On weekends, try having her lay down for a nap in the middle of the day. They are not so tired at night, and it helps them to train their minds to wake up, you have to wake her of course. Let her know what you're up to, she will be willing to try it because they want to stop more than you want them to.
