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.
