The books they grew up with. TumuBook is a reading log for parents and kids. Keep every book your child reads, with the date and how old they were. "The picture book they asked for again and again as a baby." "The book they practised reading with in first grade." Books carry a picture of who your child was at the time. Note what they read, when, and how old they were, and the record becomes a memory in itself. One book finished, and what next? With no time to look, or no quick trip to the library or bookshop, that eagerness to keep reading can quietly fade. TumuBook lays out what might come next from the books they've read: "if they loved this one, here are a few more." A natural moment to ask, "Want to try this one?" SECONDS TO LOG.
