Fantastic book called "It Hurts When I Poop" (I don't recall the author and lent the book to a friend), but I bought it from Amazon.com and I think it was about $12. It worked within 2 days!!! My daughter was terrified to go poop on the potty and it became screaming and sobbing matches - both me and her - we were both frustrated. The book describes what happens to food when you eat it and how we need to get rid of the poop to keep our bodies "clean" and healthy. I would recommend this book to anyone having potty training issues (and I have too!). Good luck!!
