our pediatrician, when my kids were little, advised just making the potty available and not putting alot of stress into it....kids will do it naturally eventually....as my doc said "you never see a 21 yr old in diapers"....every time you 'go potty' tell her that's what you're doing (she doesn't have to be in with you...just know that you're doing it)....and her natural desire to imitate you will kick in eventually....if you put alot of pressure on her it will make things alot worse...
when my eldest was toddling my mother got me all upset because she claimed she had me potty trained by 7 months old....so i got all worried and followed my poor little son around constantly bullying him about going potty....he got so upset by it all that he started hiding in closets and wetting his pants or pooping in there....hiding from me!!...he wasn't "trained" til after he was three when i finally took the doc's advice and let him be....obviously he could control it, as shown by his going into the closet, so he knew the urges etc....but my nazi-like pressure kept him so anxiety ridden he couldn't actually go in the potty....
another thing you shouldn't do is reward with candy or other treats....when i was training my daughter, we had a jar of "potty training candy" that was just for her....and whenever she went potty, we would parade thru the house singing about how she went potty, then she got to select a piece of candy from the jar....this started her on a pattern of using food as a reward....not a good thing....i recognize the same pattern in my life (my mom did the same sort of thing)....we both have significant weight problems...
and it was difficult to determine when the potty going became so normal that it was time to stop rewarding....a hug and an encouraging praise works just as well....alternatively scolding and anger won't improve the situation.... if she has an accident after she has gotten the idea, a sad look and a reminder about next time works well....
also some pretty, fancy "big girl pants" held out for when she stays dry can be a good incentive...let her pick them out, telling her that when she stays dry for a certain length of time she'll get to wear them....
just let her be....she'll catch on eventually....
