I'll add an update - DD has been in panties from her 2nd birthday (Nov 13th) and other than the occasional accident while playing and forgetting to stop, she's basically toilet trained for peeing!
We'd started doing the naked time again leading up to that day, but we did have to take a break and use diapers on a plane trip down to SC to visit my sister the week before. But the day we got back (2 days before her birthday - free plane ride for her getting it in before 2, woohoo!) we did naked time and then right into undies...Minnie Mouse to entice her. Her birthday party was already scheduled and so there was a potty in the living room and when she had to go, she went! By about a month in she was getting good at telling me so we ventured out, potty in the back seat, and if she had to go, i'd pull over in a parking lot and she would go. Then a few times FIL took her to his house and forgot to bring the potty and she had to hold it, but no accidents in the car. So now we don't bring the potty, just have her go before we leave and I've been ut for 3 hours with her and she hasn't even asked to go - although I do eyeball the bathrooms everywhere we go just in case.
Overnight - I had a few nursing home/stretcher pads that DH grabbed from work (good to be married to a firefighter lol) and we use those on the bed on top of her sheets. The first week in undies she was waking at night and using the potty completely by herself (I'd either hear her or when we got up there would be pee in her potty by her bed). Second week she would cry for help and we'd get her on the potty in time 50%. After that it was hit or miss...she'd either go the night dry or wake up crying because she was wet. There was one really bad week where there was 2 wetting per night....but then it got better. We've been at least 2 weeks dry at night although probably more, I haven't really been counting. She can even wake up, ask to nurse, I go to her bed to nurse her, and she conks back out - no potty trip before or after and still wakes dry.
Pooping....FIL seems to have f*ed that up for now as usual. She did few on the little potty and regular toilet, then he asked her one too many times and so she poops in diapers. She will ask for a diaper, then go in her room, close the door and stand in her closet....probably a result of trying to get away from FIL to gain control over the situation! ANYWHO....I've talked with her, she's not quite there, but I have hinted that the diapers fairies might come along looking for some of her old diapers (cloth) to give to new babies that need them (I'll pack them away til we're ready for another) and she's been getting excite about these fairies and talks about them coming so I think I will play into that with letters and treats from the fairies a la a tooth fairy style of trading - give up a diaper, get a treat. She's into tinkerbell so I think it's a good compromise for us but not taking them away cold turkey, it preps her for the transition, and allows her to see the change coming....and I can always pull them from the basement storage at anytime if she wigs out.
And that's where we are at now!
