At our friend's cabin upstate, Toby loved the friendly grown-ups and wanted to be in the middle of the action at all times. But Alex and I could only chase him around and keep him from falling off the dock for so long, so the sling turned out to be a perfect way to keep him happy and immersed. Here, we're fishing with friends--it was the first time for both Toby and me! (We caught nothing:)
