What's There?

Melanie Walsh presents early concepts in two lift-the-flap board books. In What's There? children find that the cat is ""behind the door,"" a frog is ""under the lily pad"" and a moth is ""near the light bulb."" A lift of the flap in Big and Little causes each picture to change into its opposite. For example, on one page, a child is at the bottom of a ladder; the opened flap shows the child's feet at the top. (Aug.)
