Don't worry, I am not about to do this. But I have been musing about risk and safety recently and I am wondering if this really is as terribly unsafe as we all think it is. He doesn't wake up and will be asleep for 90 mins or more. Even if he did, he is a sensible child and is not going to fall down the stairs or drink bleach or anything. He would be worried that I was not there (which is my main reason for not doing it).
I know the argument is "what if there was a fire?"
But there isn't a fire, is there? How many fires start at random when there is no-one in the house but a toddler, fast asleep? I can see there is a small risk here - but it seems tiny to me. How does it compare with taking children out in the car? Crossing the road? Air travel? Being savaged by a dog?
As I say, please don't think I am about to go out and leave him - I'm not. But can someone explain to me why this would be absolutely unacceptable for me to do so, because I'm not getting it.
