PRAISE him while telling him NO without actually saying NO!...Say something like "Oh you are such a big boy, I know you can do it"...Guess what? if that little darling think his hands will be yucky, imagine how his bottom will feel.You can go as far as letting him walk around with a yucky bottom without giving in, trust me he won't like it. When he starts to complain about his yucky bottom, hand him fresh underwear and encourage him to wipe, and then encourage him to use the Big-boy soap! Don't point out the negative, re-direct him to the positive. Also, buy some of that Kiddie foaming soap, the pump bottle has cute designs on it and encourage him that after he wipes himself, he can use the BIG boy soap!! Always use positives when you want to re-direct your children to do what you want. If you don't start now, as he gets older, it'll be something else that he thinks is yucky and won't want to do. Also, get some cute colorful hand towels and get a Musical step-stool to put at the sink. As soon as he steps on it, it'll play songs!! Good-Luck, this will work. If you want his behavior to change, you have to change yours...Last, buy an children's Audio book on handwashing, bathing, etc...He can listen to it while on the Potty!!Keep in touch!
