This is Luke's favorite book right now. We get to read it to him at least 6 times a day-- always at least twice in a row. Then we get to listen to Luke read it. He reads it something like this "Yes! a moon. Yes! penguin. Yes! sheep. Yes! (mumble mumble) Yes!" and so on. This was never my favorite Eric Carle book because it is sooooo repetitive. But I think that's why Luke likes it.
