basic reward system. Find something she really wants. We did stickers at first but that didn't last long. The first child we were successful with Freeze Pops every time she went to the potty (and never gave it when she didn't and not even for an attempt.) Once you get pee down then reward her for poo only. she was potty trained by age 2 1/2.
The second child loves chocolate. So we give chocolate mini bars each time she goes. Now we only reward her for poo. 2 1/2 and potty trained.
By the way, the first time she actually does it herself without you prompting, have a pee party (no you don't have to invite anyone). Jump up and down as if you won the lotto and make it a special day. keep reminding her what a big girl she is for making potty the whole day. Don't get too discouraged if she has some setbacks. Every kid has setbacks. Let your husband also have a potty party in front of her (major hugs and kisses, jumping up and down.) And everytime after that, EACH POTTY, you have to have you and your husband give her verbal praise!!!! "You are a big girl now! i'm so proud of you!"
Find out what she likes!!! don't get mad if she makes a mistake. She'll be more afraid of telling you and sit around in wet underpants. Keep it positive. When she has an accident, give a big hug and say "that's ok. You'll do it next time."
And patience. Have patience. IT WILL HAPPEN. When she goes for the first time, take her to the store (we go to Toys R Us) and i let them pick their first set of panties. I bought three packs. They've got all kinds-dora, mermaid, tinkerbell, little pony, etc.
(P.S. Oxyclean for poo stains in the panties. Or if they're really bad, just throw them out.) Daycare takes the 2 year olds to the potty EVERY 2 hours when they are learning. You'll have to do this to. I know it sounds tiring. But she probably doesn't have the strength to control her bladder yet. You are working up to that point.)
