Even if your little sprouts seem to set up a grudge match over just about everything: choosing the Friday night movie, toppled LEGO towers, and endless hours of she-touched-me-again, in the end, a brother or sister is a built-in best friend. (Who better to help drive Mom crazy or snicker with at Dad’s creative cooking?). Flip through the album to see our picks for best picture and chapter books celebrating the ultimate family bond.

Beezus and Ramona

Age: 5-10

Actually a precursor to the more famous Ramona the Pest, this endearing classic brings us sibling rivalry, Cleary-style, from the viewpoint of the older sister, Beezus (Ramona is four years old and the bane of Beezus’s existence). For sibling angst from the smaller person’s perspective, check out Ramona the Brave, third in the series.

Available at harpercollins.com, $6.99.
