Right now the household favorite is Skippyjon Jones. Seven of my library requests were add'l Skippyjon books. He's quite a little character and fun to read. Personally I'm addicted the this collections of Grimm's Fairy Tales that we have. I'd say Ivy and I are about 33% through the book. They aren't very happy and some are quite graphic, but I find them entertaining, I can hold the book with one hand, there are a bunch inside and each is only three to five pages long - leaving little room for boredom.
But my absolute favorite right now is How big is the world? by Britta Teckentrup. Adorable. I love it. I love the message. The simplicity. The depth. It's perfect for Ivy's developing sense of the world. Love, Love, Love It!
