A charming lift-the-flap book with pleasing illustrations by Bob Graham will engage readers with its slightly silly plot about multiple births. A little girl notices that her dog gets fatter and fatter, but she’s not sure what the matter is. Noticing the dog emerge from a cupboard looking thinner than before, the girl discovers that the pregnant pooch has delivered two puppies in its confines. Next, when her cat grows chubby and hides in a box, she finds three kittens under the cardboard flaps. Told in humorous rhymes, the story builds as the young girl’s mother gets bigger and bigger. The biggest surprise comes when her mama returns from the hospital with a buggy full of brothers—the number of whom will delight readers who have been keeping count. (Ages 2–5)
