"The pictures are bright and fun, while the text is simple and clear, making it perfect for younger children. The book also comes in a sturdy board book format, which I like (my son is a serial book ripper!) Both books in the Caillou Potty Training Series are a great way to start the conversation about toilet training. I really liked that it wasn't all successes in the story; Caillou wets the bed on one page, and it's not a big deal, he just tries again. Learning that everyone experiences misses alongside the hits is important for children of all ages." --Today We Did Blog.
