This felt more like it was written for parents than ever it was for three-year-olds, so I'm not convinced that this approach made sense, but each to her own! The author, who has a really perky name and who illustrates her own books quite colorfully and competently, has at least one other book out of this nature, titled Two!" (reviewed by me in March 2017).
While I thought the approach slightly odd and noted that two pages (the getting stuck in his pajamas, and getting dressed by himself) were in the wrong order in my crappy Kindle app from Amazon, the rest of the book was fine. It's very much into chanting and rhyming, and if this is your thing - or more to the point, your child's thing - then I think this book would be a worthy read. It's very short, so whether you deem that a good thing or not is up to you of course. With these caveats in mind, and at the risk of this book giving your child some mischievous ideas you may wish she or he had not been exposed to, I deem this to be a worthy read!
