The bedtime rituals of little diggers and dump trucks at a construction site should be quite familiar to kids who say goodnight. Truck-obsessed toddlers will love making the diggers, tractors, fire engines, and monster trucks featured in this bedtime story part of their own nightly routines as their mommy trucks read them one more story and their daddy trucks sing a song. With a simple rhyme scheme and adorable illustrations, this book -- along with Brianna Caplan Sayres other things-that-go-to-sleep titles such as Where Do Steam Trains Sleep at Night? and Where Do Jet Planes Sleep at Night? -- will leave children feeling snuggly and satisfied.
