So Hubs' Dad and Step-Mom live on a lake, and they'll be watching Xander for a weekend while we go to a wedding. I keep thinking about whether I feel comfortable with them taking him into the lake when we're not there or not. He'll be 5 months. I'm thinking about saying if they have an infant life jacket, they can take him into the water (and on the boat), and if they don't, then they can't. I know that they would hold onto him at all times, regardless of having a life jacket or not, but I'm thinking just to be on the safe side, to veto it if they don't have a life jacket. Is this too strict?
