There is just nothing like spending time outside. And where there's a tree, there needs to be a swing, or a low branch to use as a step. This daughter of ours understands that fact of life to her core.
Though we have the big rope swing across the little valley, these swings from our old play structure were begging to be hung again. This one found its way to a tree just outside our front door where it gets quite a bit of use. The other is still looking for a branch low enough for us to reach, but high enough to offer pendulous play.
