I finished my YOTSUBA&! reread at lunch yesterday, and friends, it's still the NICEST series. Yotsuba has 13 volumes worth of everyday adventures and I grinned my way through the lot.
My very favourite thing about it is that Yotsuba's a weirdo but NOBODY TRIES TO CHANGE HER. When I was a kid, the unusual child character always, always faced scrutiny from disapproving adults who wanted her to be More Like Them. Yotsuba's adults embrace her quirks.
