Who Said Moo?

Harriet Ziefert and Caldecott Medalist Simms Taback team up for a pair of lift-the-flap board books. Where Is My Baby? features mamas' search for their little ones, naming them as they go (""Here is my calf,"" says the cow). In Who Said Moo?, Red Rooster wants to know who answered his morning call (""Someone said moo. Was it you?"") and discovers a wide array of animal sounds. (May)
