While this book was adorable from the brief simple rhymes to the character illustrations featuring banana-fingers, a reviewer has to wonder about the advisability of subjecting a young, impressionable mind to mischievous and potentially problematic behaviors such as these! The book was so enjoyable though, that I'd advise parents to get this only after their child has exhibited most of the behaviors depicted here, to limit the risk of how many new ones they'll be able to learn from it! Alternately, maybe my diagnosis is wrong and it's aimed at parents, not young kids!
The 'terrible twos' are named that for a good reason. This is the age (give or take many months since it can begin any time from the first through the fourth birthday!) when children are starting to feel a certain independence from parents which will continue to grow and become increasingly necessary throughout their life. Couple that with a human's natural curiosity about everything, especially when that human is a child, and you have a recipe for, if not a disaster, then an extended period of trial and tribulation.
This is a time when they grow to hate hearing "No!" because they're starting to hear it so often, so maybe "No!" shouldn't be your knee-jerk reaction? Maybe a more roundabout way of employing dissuasion as well as a little less diligent policing (while still watching and keeping them safe, of course) won't turn them into hellions and will help improve relations? Obviously the more things you can find to distract them or keep them distracted, the less they will be inclined to pursue their own diversions, too.
The kid shown in this story is no different from the norm, climbing, hiding, sampling everything, running on hyper-drive, exhibiting vacillating and contradictory desires, and though it's a boy here, gender makes no difference either. Sugar and spice can be just as big of a tornado as snails and puppy-dog tails any day of the week. Sleep helps (yours and theirs!), so if you can get them down for at least half the day, with at least two hours during the day and the rest overnight, it might help.
The trick - although it can be a difficult one, is to appear calm and keep offering redirection. And remember it's not about you! It's about your progeny growing up. Even so, and with the best will in the world, kids will very effectively be kids and get up to the activities depicted here: getting into everything, climbing dangerously, picking everything up from the floor, putting everything picked-up into the mouth!
Kids are not endlessly resilient, but they are resilient and a bit of dirt here and there, even ingested, isn't going to harm them. Neither will small falls, since young bones are so pliable, and they do have to learn - somehow - that risky behaviors can be painful even if it's only a scraped knee! Of course that's not the same as letting them run riot! Curiosity can be helped with games, and even simple, home-made toys: paper bags, cardboard boxes, study plastic bottles with the lid removed or screwed very tightly on; soft toys, especially if they have zippers or pockets to explore, and so on. Even an old hoodie or a shoe (no laces!) will do for a distraction.
That's why I think this book will serve better as a retrospective; a trip down memory lane, congratulating your child on good lessons learned, and on how well they've grown, maybe how much they cried that time they didn't listen and got an injury, and how wise they've been to have avoided that since. A nice ego massage over how much their behavior has improved (even if you have to tell a stretcher here and there!) is wonderful. Positive reinforcement is always a bigger winner than negative - assuming you can even remember this when your last nerve frays!
On those grounds I recommend this as a worthy read and I'm now wondering whether this author plans on a "Three!" and a "Four!" and so on! What's going to be in the "Thirteen!", the "Twenty-One!", the Ninety-Four!"?!
