Let me tell you, it's alot easier to "prompt" boys to do peepee in the potty (pour warm water on genitals will almost always get them to peepee) and easier to get girls to "number 2" in potty.
I have an older girl and older boy. They both pt'd well into 3 yrs old. My now-3-yr old 3rd child is giving me as much trouble. He will readily get on the potty (big toilet as I hate cleaning training potty's) and do all his business. However, he will not tell me he HAS to do something or when he already did something in pull-ups.
With my older two, I was SAHM and was able to put them in regular underwear and go outside so if they had "acciden", it would not be in house and they got the drift that you get icky feeling when you potty in your pants (with diapers and pull-ups, the lining pulls peepee from skin and they dont GET IT when they did accident). With my 3rd child, I'm a home daycare and cannot let him (or the 2 yr old daycare kids) run around in reg. underwear.
I just this week started the chocolate prize for "number 2" in potty. I'll remind him in the mornings and at lunch... for 2 hours after reminding him, he's pulling my hand to follow him to potty, lol, and mad when he can'd "do the deed" on the potty!!
Hang in there, don't pressure her... if you are REALLY into potty training, as I'm NOT, only give fluids at certain times of the day (not an endless, bottomles sippy cup... just at meals & snack time) then you'll see a pattern of needing to potty and it will help you to get her there in time.
Good luck!
