Hi M.,
I wish you luck! I believe when they are ready to potty train, it will happen. I decided when my child had been completly potty trained during the day, I would potty train at night. I would place a set of sheets on the bed, cover with a plastic sheet or waterproof sheet and another set of sheets. All I had to do was wake up and pull off 1 set of sheets, clean up my daughter and back to bed. Well after doing this night after night, I decided.......is it really worth it? Is one diaper a night going to break my budget? My daughter would litterally tell me...."I love my diaper", even though it was only 1 in 24 hours. If it was up to me, I would talk with your daughter about it, but leave it up to her. When she becomes dry again thruout the night, ask her how she feels about wearing undies at night instead of the diaper. I promise it will happen. Once my daughter decided it was time to get rid of the diaper, she let me know. Guess what? Not one accident since she decided it was time. She is 9 years old and still potty trained.
If you decide to continue potty training. Try not to show any anger or disappointment, if an accident does happen. You may want to set a clock to wake her 1 or 2 times a night to go pee. This would help but you will be back to not sleeping thru the night again.
I hope this helps put things into perspective. I wish you luck! Like I said, it will happen some day. Sometimes I wish my 9 & 12 year old were back in diapers. They tended to not argue as much as they do now!
