The dock and ladder provide excellent support for getting out of the pond without having to walk through the slime–especially when you are practicing all sorts of ways to jump in.
Even the big kids use it. 🙂
Of course there is also the support of the floaty bathing suits, which keep the kids safe in the deep water.
And sometimes you need the extra support a kick board will give.
