As I think I mentioned in another post, I enjoy sharing books I loved as a child with my nephews and nieces, seeing the stories afresh through their eyes. It's also nice to have a valid excuse to reread books that I still love after all these years. My sister told me that she was reading some Winnie the Pooh to her boys a few weeks ago, and was tearing up when reading about Christopher Robin going off to school. I've done that myself, and I think that great children's fiction should have something to say to adults as well as kids.
Occasionally the munchkins introduce me to a great new children's book which I haven't read before, which happened recently. One of my four year old nephews has become a fan of the Mercy Watson book series, and I've read a few with him. They're authored by Kate DiCamillo, who is well-known for several of her other books which include The Tale of Despereaux and Because of Winn-Dixie. I had never read anything by her before, but her Mercy Watson books are delightful. Mercy is a pig who has a variety of adventures in the book series. There are also some other books which aren't directly about Mercy but are set on the street where she lives. These books are well written and fun to read for kids and adults.
