Partnering up for a simple yoga session is a playful way to help your child keep her mind and body balanced. Even better, it doesn't require much setup, just a nonslip yoga mat and a wide-open space. Shari Vilchez-Blatt, founder and director of New York City's Karma Kids Yoga studios for children and families, recommends getting started with these three poses. "They offer loads of benefits, such as improved strength, flexibility, coordination, and confidence," she says.
