Hi! 

A string of comically stylized animals greet each other in masterfully rhyming coupletsan owl’s ‚;hoo‘ is answered by a cow’s ‚;moo‘; a crow’s ‚;caw‘ is returned with a donkey’s ‚;hee-haw’all leading up to the ‚;hi!‘ and ‚;good-bye!‘ of a human toddler and his mom! The first in a brand-new board book series on animal (and human) first words by award-winning author and illustrator Ethan Long.
