I agree give pull-ups or training pants the flick - we said 'good-bye' to all the nappies, DD helped me put them in a bag and we pretended to throw them in the bin. We went straight to undies day and night so there was no confusion. The program works on the theory that your little one won't like feeling wet so will learn that when they feel they need to go, to get to the potty otherwise they will get wet. Training undies and pull-ups don't have the same affect as they contain the wetness itms?
