Five squirrels, and not one of them is the right one. Its nose is too soft, its chest is too fuzzy, its ears are too furry, its paws are too rough, and a baby gets to test every claim, because each squirrel carries a real textured patch bonded into the board page.

That is the whole engine of the series. Bright, bold shapes a baby can actually resolve, one word of difference per page, and repeating text that turns story time into call and response long before a child can say the words back. The little white mouse hides somewhere on every spread, so there is still something to find once the stroking is done.

Ten thick board pages from Usborne's touchy feely list, illustrated by Rachel Wells and set among autumn leaves and spinning sycamore seeds, for hands from three months up. A first sensory book built to survive being chewed, and the kind a baby asks for again the moment it ends.
