This is a very cute story! I bought this for my son when we were trying to potty train him. I read this book SO many times in a day it was insane, he loved that book so much and carried it all over. It helped immensely that he was into trains at the time too. It definitely helped him with potty training and it was worth every penny. I wanted to buy it from my other kids too, but I couldn't find it in stores any more..
