[Any] task is much easier if you have the tools. Do/did you have a baby monitor? A technological tool, that allows you to "monitor" the baby while not being within an arms reach.

Do you have an A+++++ oven with three panes of glass? It's [relatively] safe to touch and instead of monitoring if a child is somewhere near the oven you have to monitor if the child does not actively open the oven. That's much easier.

Dumb question, not a parent — how old does a child have to be before they'll only touch the hot thing once so you don't need to guard it?

They learn to not intentionally touch the hot thing between 1 to 2 years, but then they still can fall on it or hit it during play.

As a parent you quickly learn that when you don't actively prevent major accidents it ends up costing you much more time, stress, screaming, etc.
