The Tactile Advantage
Most board books with moving parts are a gamble. You buy them on Tuesday, and by Thursday, the flaps are torn off and the 'interactive' elements are in the recycling bin. I Thought I Saw a Dinosaur! solves this with sliders that are built into the page structure. They move horizontally or vertically within a track, which is a much more natural motion for developing hands than the pincer-grasp required for delicate flaps.
Design Matters
Lydia Nichols is a fantastic choice for the illustrations. The colors are bold without being neon-bright, and the character design is charming. It’s part of a broader series (including penguins and elephants), but the dinosaur version tends to be the gateway drug for most families.
Literacy Context
At this age, reading isn't about decoding letters; it's about the 'Language Comprehension' half of the Reading Rope. This book hammers home spatial vocabulary—'behind,' 'under,' 'inside'—which is the foundation for verbal reasoning later on. It’s a low-stress way to build background knowledge about how stories work: there’s a mystery, a search, and a resolution.
If your kid is in the 'do it again' phase, this is one of the more tolerable books to have on repeat. It’s fast, tactile, and the art is good enough to stand up to the hundredth viewing.
