Potty Train your child in one day by Teri Crane. We used it with our 33 month old daughter and it worked. Completely trained in one day using a potty party, had one accident a day for about 4-5 days, then maybe 2 accidents after that, and both of those were because we hadn't thought to put a potty in the attic and basement where she has play areas. Now she can hold it long enough to get downstairs, but in the beginning, you don't have much time between "I have to pee" and the event itself. It's been about 3 months now, and she's dry through the night, though we still use a pull up at night--just in case. We don't use pull ups for naps or in the car (but do stop about every 2 hours on long rides), and haven't had any problems. It's a great system, but your kid has to be completely ready.
