I have 8 years of day care experience working with 21/2 to 3 year olds, so i've helped lots of families potty train their children. My best advice is to ditch the diapers! Pull ups don't work very well either (use at bedtime only). When she has an accident ask her where her potty goes and remind her that it goes in the toilet. Just deal with the accidents. She will probably have quite a few the first 2 days but you should see improvement as the week goes on. Have her sit about every 2 hours, every hour is a little excessive. Never get angry and use lots of praise when she does go in the potty. Get overly excited and sing and dance. you can give stickers or stamps when she goes (i recommend not using candy). When children are ready it shouldn't take longer than 2 weeks (in full time underwear!). Even if you go to the store or on along car ride do not resort back to diapers or pullups. have her sit before you leave, at the store, make frequent stops to the gas station. if you're worried about her carseat getting wet you can use a towel or they sell car seat protectors at the store (target i know sells them). stay positive, be patient, and stick to the big girl undies! good luck!
