my 3 yo son is having no trouble with daytime pottying. He has potty trained there for months. We found the only way to accomplish that part was to take his pull ups away and make him wear real underwear, otherwise he just wet his pull ups 'cause he knew he didn't have to stop playing to go potty, he could just go in his pants. We have no problems at nap time either, but night time is a problem. My husband works out of town sometimes and during those times I allow my son to stay in my bed for the night. He never wakes up wet when he sleeps in my bed, but the second he goes back to his own room, he wakes up with a wet pullup every morning. We have tried limiting liquids, making him go more often in the evenings to the bathroom, nothing seems to be working. I am glad to hear about the two sets of sheets ideas to make middle of the night clean up easier, since we feel our next step is to just take the pullups away at night like we did during the day. Anyone think this is a good idea???
