Here's a birthday celebration that will leave everyone cheering. When I hosted the party for my then nine-year-old daughter, Maddie, and eight of her friends, the girls were delighted with the crafts, snacks, and high-energy games. Our party plan takes all the guesswork out of throwing one for your own pom-pom shakers, featuring a spunky invitation, crafty pennant making, a concession stand for snacks, a megaphone cake, and the star attraction: a real cheerleader in uniform. Team these ingredients with a group of spirited kids, and you've got something to shout about!
