My in laws have a new house with an open access backyard pool. There is a fence around their property but no isolation fence around the pool. I have a 2.5 year old, walker, and a 9 month, crawler. Problem is, the in laws don't see the lack of isolation fence to be a issue. They don't want a fence for aesthetic reasons. But they have no other safety measures like door/pool alarms or even a safety lock on the house door to the backyard. I am very nervous about taking my kids to their house this summer. I am wondering if anyone with a pool or family/friends with a pool has suggestions for realistic safe guards around a pool. It's a great undertaking to expect me to be so vigilant to never let two kids out of my sight while at their house.
