If you're a big sister, you probably know lots of things already. But when it comes to little sisters, every girl could use a few extra tips! This guide covers important topics like "cuteness" (thank goodness she's the cute one now - what a hassle that was!) , "tickling" (includes handy cutout that details ticklish spots) , and "sharing" (one cupcake for her, two for you) . It's the book no sister should be without!
