in the First Feelings series from Clever, is the perfect way to introduce children to emotions. Toddlers can lift the flaps to see some things that make Unicorn and her friends feel angry, such as Bear taking Unicorn's favorite sand toy; Alligator watching his tall block tower fall down; and Frog getting his kite string tangled up. Children are invited to talk about what makes them angry, too, and some things they can do to help calm themselves down when they feel angry.
