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.

Max’s Dragon Shirt

Age: 3-7

Ruby and her little brother Max, that rascally bunny of few words, take an adventure-packed trip to the department store. Although their mother gave them five dollars to buy a new pair of pants for Max, they end up coming home with something very different. As in all their books, Max is stubborn, Ruby is bossy, but together, they’re somehow the all-American brother/sister combo of our imagination.

Available at indiebound.org, $5.99.
