Let your kids fail. To learn self-sufficiency, kids need to occasionally dust themselves off (literally and figuratively) without your help. "Most parents know what their children are capable of but step in to make things easier for them," says Sheri Noga, the author of Have the Guts to Do It Right: Raising Grateful and Responsible Children in an Era of Indulgence. Remember: Long-term benefits—a teenager who knows how to do her own laundry, for example—trump momentary discomfort. Before you rush in to help with any physical task, ask yourself: "Is my child in real danger?" Then—and this applies to other challenges, like the social studies poster due tomorrow—think about whether your child has the necessary skills (dexterity and balance) or simply adequate sleep and a snack. Yes? Time to back off and see what happens.

The match is helping to raise funds and awareness for the charities supported by the two princes, according to Kensington Palace.
