Book Review: It's Time to Say Good Night

I got this book at the library. It's simple but poetic, and you can read it once, and then twice, and then three times (which my son requests), each time getting faster which makes it fun.
It's great for little boys too, because the boy in the book says good morning to the farm animals and the "things that go" like planes, buses, cars, trucks. He says good morning to so many things that when he's done it's time to say good night to all those things. And then on the last page, most of those things are things inside his bedroom- hanging from the ceiling, toys, on his bedspread, and out his window.
