Hi J.,
My daughter is now five, but what I did with her worked great. I put a gumball machine (like the kind you find a Wal-Mart) on the bathroom counter. I know that seems like an odd place for a gum ball machine, but hey...it worked! We filled it full of jelly beans and everytime she went potty, she got to put in a quarter and get a few jelly beans. She loved it
and it worked wonders for us!!
Good luck!
