It's Not Fair

In this book, a little girl complains that her baby brother gets away with sorts of misbehavior that she's told she can't do, because she's a big girl. She can't make messes or yell without being corrected, but the baby is allowed to... On the other hand, she realizes, she gets to do all sorts of things the baby can't - stay up late, go to school, etc. Eventually she decides it's okay that she's not a baby anymore, and she looks forward to her brother growing up, too. These issues have been explored in many books before, but this one is pretty nice, with a fairly skillful story arc. The artwork, with the little girl as an orange, cartoonish kitty-cat, is appealing as well. (ReadThatAgain)
