I made this post two and a half months ago:

I followed all the advice I received. We continued with the break, as planned until after she turned 3 (it was a 10 week break, which ended April 5th), and during that time we made little mention of the potty and tried to take the pressure off as much as possible.
Since we've gone back to potty training, I followed the advice given (don't ask if she needs to go, just tell her it's time to go, make her go before eating, before outings, etc, and have her clean up after all accidents, remove diapers and pull ups completely from the house, make sure parents and grandparents are on the same page, etc). She has had good days and bad days, and ups and downs, but ultimately, in the first 3-4 weeks we saw definite progress, and now, the last two weeks have been a huge backslide.
The first 4 weeks she was actually telling us when she needed to go, and had relatively few accidents. And when she did have an accident she helped clean up everything, and I stressed how much faster it was to go potty than clean up an accident (get back to playing faster). Most of her accidents were poop related, not pee during that time.
The past two weeks she has not been telling me when she needs to go. I had developed a bit of trust in her because, for the previous 4 weeks, she had been so good about going pee when she needed to, and she often would go 2-2.5 hours between using the potty without accidents. But the past two weeks she hasn't said she needed to go, when I gave gentle reminders (after 2-2.5 hours) she got very upset and insisted she didn't need to go. When I matter of factly say now it's time to go (because we're going to the park, etc), she fights me tooth and nail and screams and cries. She has had multiple pee accidents every day for the past two weeks, and several of the days she has had more accidents than she has had successful pees in the potty.
I've heard that her parents and grandparents have had some successes but mostly very similar struggles.
Is there any advice left to give??
