My son's very favorite book when he was around 2. He laughed when he could see the net animal through a door or crack in the wall. It's just great. Best of the Peek-a-Boo board books and we still have his copy for my grandson
Each page of this bright, sturdy board book contains a differently shaped hole through which children are invited to peek and [point out the simple object or animal on the next or preceding. Great fun!
