· Ensure the swing set is erected at least 6 feet away from any building or fences. Position the swing set in a shaded area, so that surfaces won't get too hot to the touch. Use sand or pea gravel, or a rubberized surface under the swing set, as these materials absorb the impact of a fall much better than dirt or grass. Make sure toddler swing sets are at least 2 feet above ground so kids can't use it on their own
