Frustrated and don't know how to get over it

[PreggersagainOMG]

I have a daughter, 26 months old. Goes to nursery most of the week, another child was potty training, my daughter was showing interest, sitting on potty, letting us know she needed a wee etc, so after a few weeks of this we decided to try potty training. She was doing brilliantly, dry days no nappys, thought we'd cracked it, then, all of a sudden, it's as tough she's got fed up of trying and just blatantly stands there and wets her self! I just don't know what to do? Do I just carry on, or let her have a break, n try her again in a few months? Please help, I'm at my wits end.
Thanks in advance xxx

Snap! I have put her back in pull ups for the last week or so and she has started asking for big girl knickers again. Nursery also told me to make no fuss when they wee on the floor but make lots of positive comments when they go in the right place. We are not there yet but I am hoping it works. One if my friends had the same thing and after a month the interest came back. Good luck
