S.B.
i went through that same thing!! i actually set up a reward system with my son. i had a little jar of m and m's that i made look really special with a ribbon around it and his name. if i remember correctly, i think i even had him decorate it with me??? Anyway, every time he wiped himself without my help, i'd reward him with 5 m and m's. after about 2 weeks, it was a regular thing and no candy was needed! :) good luck!! :)
