All three board books are great. My newborn loves the rhyming sounds and the rhythmic meter of the text. Pajama Time is the best of the three, but Barnyard Dance isn't far behind. Dinosaurs isn't as good as the other two, but it's still worthy of the collection. Sandra Boynton in general is fantastic for small board books (The Belly Button Book and But Not the Hippopotamus being my two all-time faves) and you can't really go wrong with this collection (unless you let your kid eat it).
