This is a good book for little ones and bigger kids, too. Lots of content (maybe too much info for the littlest ones, but you can easily omit some of the words as you look at the book with young toilet-learners). Nice pictures. Not only does it explain the usual how-to-use-the-bathroom content, it also explains a bit about where the contents of the toilet go after you flush and other questions I haven't seen answered in other kids' books. Also, it reassuringly addresses common worries toilet-learners experience. The character of Angus the Answer Dog is friendly and appealing. Recommended!
