Sally Sore Loser
Ages 4–7Sally hates losing so much that she yells, bosses and sulks, until she finds she’s playing alone because no one wants to join a sore loser, and a kind teacher helps her learn how to be a good sport. It names the behaviour plainly and shows the cost of it, with helpful notes for you at the back. Good for the child whose competitiveness has started to cost them friends.
