Would a daycare like this make you a little nervous? Even though it sounds fun?

Even with a life jacket, an adult should have a hand on every child at all times for all non swimmers. I was a lifeguard and a Water Safety Instructor for 10 years. A child should never be left to float alone without an adult holding on until they can swim completely independently.

I agree. I didn't mean to imply life jacket in lieu of adult contact. I would never use a life jacket without an adult in a body of water. I use them on my children walking along a dock or playing at the edge of the ocean if it is rough. For me it is a "keep your head above water until I can snatch you out".
