Anyone who's seen kids on a playground knows that most are naturally physically active and love to move around. But what might not be apparent is that climbing to the top of a slide or swinging from the monkey bars can help lead kids to a lifetime of being active. And even if kids have the time and the desire to be active, parents may not feel comfortable letting them freely roam the neighborhood as kids did generations ago. So their opportunities might be limited. In spite of these barriers, parents can instill a love of activity and help kids fit it into their everyday lives. Doing so can set healthy patterns that will last into adulthood.
