DS will be 3 in June and loves the water. We go to the cottage or my parent's house every weekend in the summer and spend most of our time in and out of the water. The water is very shallow and DS loves to jump in off the dock and splash around. I'm starting to think about my options for LO #2 when DS wants to play in the water. I'm thinking a carrier of some kind is the key, but what kind is best? I obviously wouldn't be going very deep, just far enough for DS to have a little fun and for me to supervise safely. Do you have any recommendations?
