F.W.
I used to work in a daycare center with 2-2&1/2 yr olds, right when they were potty training. One trick that some moms used was to take there child shopping and pick out some really cool "big-girl" panties and make a big deal about how special they are and that she cannot mess them up by wetting them. This way she feels she's accomplished something special, won't want to mess up her new panties and won't want to go back to wearing diapers.
