Is very graphic, so not for the faint hearted parent :-)

Has pictures of breastfeeding, poop, boys standing to pee, etc.

This book and "My Big Boy Potty" are the best books I could find on potty training. Realistic situations addressed.
My son appreciated the introduction reviewing that he used to be a baby and needed lots of help from mommy and daddy, but now that he is growing up he can do big-boy tasks. This helped him feel that going pee/poop on the potty really were events that helped differentiate him from babies.
Good photos - appreciated the attachment parenting references.

Many of this book's positive qualities have been discussed already, but I will mention my favorites again: I like the simple pictures (which we all know will hold a toddler's attention better than more detailed drawings), the fact that the child in the book could be either a boy or a girl, the sidebars with answers to questions that undoubtedly will pop up ("Where does poo-poo come out?" "Why won't my poo-poo come out?"), the "tips for parents" on potty-training, and the fact that the child in the book is not punished for having an accident and not making it to the potty in time. And I love the fact that the potty in this book looks like a modern training potty, rather than a lemonade pitcher! This is a very loving book with two very loving parents and happy-looking older siblings.

However, this is not the best potty-training book out there. First, it's too big. I know this might sound silly, but little hands like little books, and my daughter grew frustrated when she tried to hold the book in her lap because it would not fit. Instead she would always choose Joanna Cole's book My Big Girl Potty (there is a boy version too) - it was the perfect size out of all the books we chose. Second, this book has too many words, so it doesn't hold a toddler's interest. My daughter would reach to turn the page before I could finish reading half of the writing on the page. Third, it shows a woman breastfeeding her infant, which is wonderful but my daughter has not seen me breastfeed because I am physically unable to, so this picture could confuse her. Fourth, the book also shows the mother emptying the "contents" of a diaper into a toilet, which I do not do since we use disposable diapers and I don't have time. Fifth, the book also shows an older brother peeing while standing in front of the toilet. I do not want my daughter trying to pee while standing over the toilet one day - think of the mess she would make! I know I could explain to her that boys pee while standing up, but still, she would want to try it herself!

I recommend Joanna Cole's book over this one. Also, if you have a little girl, check out The Princess and the Potty by Wendy Cheyette Lewison, which encourages girls to potty-train so they can wear pretty panties! Hey, it works!

We love this book. We love the chart. My daughter really enjoys "reading" the pictured steps for going to the potty. Having said that, I would like to point out that children of 2+ years are still learning about sequential steps. The chart is often confusing because Step 1 is aligned to the left margin; Step 2 bounces to the right margin; Step 3 aligns left again, etc. While this makes for a cute layout... I've noticed that my daughter will frequently recite the steps down Column 1, then go down Column 2 (at least to her they look like columns). Then she gets a confused look on her face, because she KNOWS that you have to pull up your pants BEFORE you wash hands, but the chart "reads" differently. Anyway, we keep rehearsing it and she'll get it eventually. But the chart designers could have saved us that headache by taking into consideration their very young and "literally" minded audience.
