Andrea Beaty's Questioneers vs. Kit's Little Sparks: Which Age Is Right?

If you have a curious preschooler, you have probably heard of Andrea Beaty's Questioneers: Rosie Revere, Engineer; Iggy Peck, Architect; Ada Twist, Scientist; Sofia Valdez, Future Prez. They are beautiful, popular, and they work.

People ask me if Kit's Little Sparks is the same kind of thing. The honest answer: same family, different age. Here is how to think about which one to buy.

The Questioneers are picture books for ages 5 to 7

Andrea Beaty's books are picture books, typically 32 pages, rhyming text, a narrative arc with a satisfying conclusion. They are designed for a child who can sit through a story, follow a protagonist through a problem, and parse a moral.

That is roughly ages 5 to 7. Kindergarten through second grade. The vocabulary, the structure, the emotional complexity, all calibrated for that window.

Kit's Little Sparks is STEM books for ages 2 to 4

Kit's Little Sparks is the prequel age. Twenty STEM books, 8 by 8 inches square, one or two sentences per page, built for a toddler who can hold the book on their own lap and come back to it the next morning. Available in ebook, paperback, and hardcover. The board book edition is on the waitlist.

The structure is different too. Instead of one long arc per book, there are five developmental phases across 20 books: Wondering, Making, Sharing, Growing Together, Becoming. Each phase has four titles that build on each other.

How they fit together

If your kid is 2 to 4, start with Kit's Little Sparks. You will have plenty of runway to grow into the Questioneers around kindergarten.

If your kid is 5 to 7, the Questioneers are exactly right. Add Kit's Little Sparks if there is a younger sibling.

If your kid is right between (4 to 5), you can run both. Read Phase 5 of Kit's Little Sparks (Becoming) at bedtime alongside Iggy Peck during the day. They reinforce each other.

What is in common

Both series share the same belief: kids should see themselves as people who do interesting things, and the way to get there is to put characters who do interesting things in front of them, repeatedly, in books they will ask for again.

Both feature diverse casts. Both build vocabulary the kid will use in pretend play. Both lean into failure (Rosie's flying contraption falls; Kit's invention breaks in Book 7). Both treat the small child as capable.
