Lovely little book.
My 18 month old grabbed it out of the book boxes at the library and wouldn't let go, so clearly it was coming home with us. He and big brother (three and a half) both really enjoyed the silly little rhymes and telling me what animal sound came next. The meter's pretty good, and the illustrations are appropriately goofy. "The cow says moo. The sheep says baa. Three little pigs say la la la."
Great for babies and toddlers. Older children would likely find it juvenile unless they were reading it to a younger sibling.
