Potty training is not simply the end of the diaper nuisance; it is an opportunity for a toddler to see his parents as happy agents in an important step in his life. Lead him through the process, perhaps directly following the order of events Capucilli uses. Her simple rhyming, and Stott’s fun illustrations, touch on numerous aspects of potty training, making them explicit for your child. To you it may all be obvious, but to him it is not. Help him out, read the book, read it to him, and then help him follow through.
