Hi all - thanks for the encouragement! So the waking up to go potty was short-lived. She has since progressed to simply peeing in the bed without waking up and then staying wet all night :(
We've always had a waterproof protector on her bed (crib/ toddler bed and big bed) as well as night lights in her room and the bathroom, and we now have everything set up for her in the bathroom (potty seat on the toilet, step stool to get up there as well as a second step stool to reach the basin to wash hands) - but she doesn't wake up on her own to use it.
We've woken her up to take her and this worked for a few nights, but then she started screaming and crying about being woken up, so now we've given up on that. So after bathtime, we ask her to put on a Pull Up - if she's not agreeable (most of the time she is!), we put on panties and tell her we'll be waking her to go potty. Depending on the circumstances that night, we then either put on a Pull Up after she's asleep or wake her up to take her to the potty. To our dismay, we've discovered she has a big bladder and has to be taken twice - midnight and around 4am - in order to ensure no bedwetting, despite restricting liquids before bedtime.
The current 'agreement' we have with her is: if she wakes up three nights in a row without peeing in the Pull Up, then she can wear panties all night. The funny thing is, the very first morning after we told her this, she said, "I *am* dry", insisting she had not peed - of course, the Pull Up _always_ feels dry, so we had to show her an unused Pull Up to convince her otherwise! Anyone know of a diaper/ pull-up that _doesn't_ keep baby dry?! (No, the 'cool alert' Pull Ups don't register with her either...)
