H.S.
My twin boys are almost 3, and are in pullups for long trips in the car and at night. This started with one of the boys showing his readiness with using the toilet -we would ask them almost every 2 hours if they had to go potty, and just let them sit on the toilet to get use to it. After about a week or so they were telling us that they needed to go potty. They enjoy flushing the toilet afterwards and washing their hands. As soon as one of the boys started going regularly, he saw all the praise that he was getting, and initiated going potty on the toilet by himself. Hope this helps!!! Good Luck!!
