A baby's hand goes to the lamb's nose before anyone has read a word, which is the whole design: it is a real patch of texture set into the board, not a picture of one. Turn the page and the next lamb is wrong too. Its hooves are too bumpy. Its spots are too fluffy. Five lambs in, the right one finally turns up.

Fiona Watt built the series around one word of difference per page, so the sentence a grown up reads is nearly the same every time and a baby learns to supply the ending long before they can read it. Rachel Wells keeps the shapes big, black outlined and high in contrast, which is what a very young eye can actually resolve. The little white mouse is hiding somewhere on every spread, and finding it is the game that keeps going after the stroking stops.

Ten board pages, thick enough to survive being chewed, and Usborne puts it at three months and up and calls it a first Easter gift. On our shelf that puts it right beside Peek Inside Springtime, which is where the same basket usually ends up.
