Isla's Family Tree

Isla does not want new twin brothers, and she's not shy about it — which makes her eventual change of heart feel earned rather than forced. Katrina McKelvey builds the story around a paper-craft family tree activity, which is a smart move: kids can make one at the kitchen table right after storytime. The emotional arc is warm and child-accessible without ever feeling preachy. One thing to know going in: the illustrations quietly depict diverse family structures including same-sex parents and an adopted child, presented as ordinary without commentary. That will be a natural fit for many families and a prompt for conversation in others. Lovely intentions, modest literary ambition — a gentle but unremarkable addition to the sibling-arrival shelf.
