It seriously took one day...after that initial hoopla, it was just consistent praise. Once he went potty on the potty once, diapers were gone. He was in big boy undies. If he had an accident he was not comfortable in wet pants and that further helped the cause of potty training. If he wet his pants we didn't scold him we just acknowledged how yucky it felt to be in wet stinky pants. He got it. It was as simple as that. For the next couple of weeks we had a chart next to the potty and every time he went he got to choose a sticker and when he got to the end of the row he got to pick out some candy (aka Fruit snacks) from the prize box. (Also, we didn't give him a choice as to when he went. He HAD to sit on the potty after he got up in the morning until he went. We then had him try every hour for the first couple of days just to get him into the habit, but we never asked him IF he wanted to go. It was "Time to go potty" period. He also HAD to go before we got into the car. We also had his sister go just to drive home that everyone goes potty before we get into the car!!) After a while rewards weren't necessary and he was just a big boy in his big boy pants. We never had much issue with bed wetting either, but you can use pull ups at first, but the same rule always applied...wow, being in a wet smelly bed isn't fun is it? (It's a pain for us initially having to wake up and change sheets, but it gave him a lot more ownership over his choices and potty training)
I was watching the show that day and and TJ said to me from across the room..."Look, that Bald Man does Potty Day parties too! When do you get to be on TV?" TJ thinks I'm famous! Of course Dr.Phil added the HUGE deal of Thomas the Tank Engine calling the little boy...our TJ is actually named after Thomas the Tank Engine (his sister picked it out when she was three...) And TJ saw that and said..."Thomas can't us a telephone...he doesn't have any HANDS!" I was relieved that he didn't want to know why Thomas didn't call him! Nice Touch though Dr.Phil...
