On a related note. Don't assume if your child slips/falls into a pool, you will hear it. I happened to see my daughter step off a ledge in a hot tub once and she just vanished. Not a sound. If I had been facing the other direction, I would have had no idea.

As a child before I could swim I slipped and fell into a pool at a party at my grandparents house full of adults. A teen, who was inside the house, is the only one who saw me. He ran outside, dove into the pool, and saved my life. I remember my mom being hysterical and the teen being treated like a hero. I don’t remember his name he was a neighborhood kid known by my grandparents. (Maybe he cut their yard idk)
