So. Enter Satomi Ichikawa's La La Rose, set in Paris' Jardin du Luxembourg. Stuffed bunny La La Rose is "the inseparable friend of Clementine." But one day she falls out of Clementine's backpack during a visit to the Luxembourg Garden. Even though La La Rose must endure the trials of being tossed in the pond, losing her skirt, tumbling down a hill, being picked up by various strangers, she finally finds her way back to Clementine. In the process, we get a tour of one of the world's most famous and beautiful urban public spaces.
My 2 year old loves this book, perhaps because the ending is so comforting. Personally, I wouldn't mind being lost in the Luxembourg gardens for a few hours, myself. For kids who love maps (don't all of them?) the author has provided an illustrated map of the garden in the end pages.
I realize linking to Wikipedia is pretty cheesy, but the pages for the Jardin du Luxembourg have some nice photos and links to other sources.
Little Kid says: Bunny book, again!
