When my youngest daughter was potty training
I bought her a really cheap piggy bank and called it a POTTY BANK! Every time she successfully peed on the potty, we gave her 5 cents. When she pooped, she got 25 cents! She was so happy to get the coin and put it in the bank. After a two and a half weeks she had earned a lot of money...AND...was completely potty trained, so we took her to the store to buy a POTTY PRESENT with all of her money! Besides cleaning up an accident here and there, the whole process was painless.
