She's running you in circles and you need to put your foot down! Put her in big girl undies, get the daycare to do the same. Take (don't ask) TAKE her ot the potty every hour. If she can remain dry all day, she can be potty trained. Don't give her a choice. If you listen at her daycare, they don't ask if she wants lunch, or if she wants to nap, or if she wants to potty. They will say 'Hailey, time for lunch' or 'HAiley, its potty time'. They don't give her an out, they just tell her its time nad do it.
Set a timer for ever 45mins or hour. When it goes off, its potty time. Put up a sticker chart and when she goes she can put up a sticker, and buy those big (like doctors office size) stickers for poops. Its ok to 'bribe' her right now, she won't need a sticker or M&M to use the toilet forever.
She's ready, you need to just give it a push. I think alot of parents sit around and wait for thier child to do it on thier own, but what do your kids learn without guidance and support? Not much.... so you need to help her. Be her guidance, teach her what to do, and be firm. You don't have ot push, but you do have to let her know that this is how its going to be, she will use the potty.
