Hi there

Your DD sounds like she is doing an awesome job - very early to be trained day and night. From what I have read it is very normal for them to regress, even more than once so I guess you just have to decide whether you go back to pull-ups to save sanity or to keep trying and hope it clicks.

My DD has just turned 3 and has been day trained for about a month and a half and night trained for about 3 weeks. She has accidents sometimes but it's 99% of the time as she is waking. AS she usally only gets her special cover on top of her sheet I don't mind cause I wash everyday anyway but if it was during the night or getting her doona and everything else wet I would def go back to pull ups.

The other thing I ahve read is that it isn't considered "bed wetting" until they are 5 so it's quite normal to have accident up until this time. Sorry I haven't been much help but I think it sounds like you're doing everything you can and she might just get better again.
