Fabulous book for bed time. It keeps my 3 year old's interest but the rhymes and the way the story flows is perfect to mellow him out.
He gets really excited about pointing random things out in the illustrations while I read anything, which I love, but not so much at bed time because I'm trying to calm him. He pointed things out in this book at first, but when I said the first, "good night, truck, goooodnight" he fell into the rhythm and instead of going bonkers for anything but the words he was waiting for that line about each truck. And he said each one calmer and calmer following my suit.
