Hi J.,
My suggestion is to put her to bed at her usual time and then wake her up later (like midnight or whatever time works for you) to go to the bathroom. My son is now 5 and was day potty trained at 2.5 yrs old. However, he got "hooked" on the pull-ups at night (who wouldn't, they make them so much fun to wear, Diego, Cars, you name it : ). Anyway, I decided finally about 6 mos ago that enough pullups. So we'd put him to bed w/ the pull up but then wake him up around 12am (I know this sounds rough but I think it works!) to pee. He'd do his thing and then most days wake up dry. So then we graduated to wearing undies to bed but continued to wake him at night. We did that for about 2 weeks and now he's been done w/ the pull-ups and we don't even need to wake him up anymore to go. I think we "trained" his bladder somehow!!! I hope this idea works for you. I have an 11 mos old also so I was usually up late at night tending to one of his needs....you know, we never get to sleep! Good luck and let me know how you make out! My only regret is that I did not try this method a year ago!!! I think the whole pull up industry is a scam and prolongs full potty training.
Take Care,
Becky
