Right from the endpaper at the front of the book, I start reading the names of those dinosaurs and start laughing out loud.
Also, I very much like the style of the illustrations --distinctive, sprightly, and just a little bit funky.
The main character, Monkey, has developed stalling tactics for bedtime. These will likely seem familiar to most of us Goodreaders. My fave went, "It's too dark in my room."
That counting solution to sleeplessness is beautifully presented, and not a bad thing to teach a child. Not a bad thing at all.
