At some point, every toddler pretends to be able to fly. This fascination with flying and the machines that do starts early and can last a lifetime. In the latest entry to the Sesame Subjects library, Grover and Elmo cater to that interest by telling kids about all kinds of machines from airplanes to rockets. Toddlers learn the very basics of how these machines are able to fly, how people help them do it, what planes and rockets look like inside and out, and the many ways in which they’re useful to people. The book is filled with terrific photos of all types of planes and rockets, loads of fascinating facts, and much more to fascinate even the most curious of toddler.
