Try rewarding her with a treat like a sticker or a single m&m. My husband and I would always make a huge deal and sing and do the pee-pee dance when our son was 1st starting. We would also let him call someone to tell them, lol. My poor mother got many a pee-pee call. So did some of our friends that he chose at random. We always just made a big hoopla out of it and never criticized an accident. He really wanted to go to preschool so that helped too. Good Luck!
