I bought this book for my 20 month old nephew and can’t believe how much he loves it. He rarely plays with the same toy for more than five minutes. But Barnyard Boogie keeps his attention all day! You can’t really tell from the picture, but the mouth of the donkey is a hand puppet. Every page has a different animal; you can put your hand in the back to move the lips for each animal. My nephew really loves putting his own hand in the puppet and making his own animal sounds. Too cute!
