Lol Mm, that's like a babysitting job my first proper b/friend and I had
You can't imagine it now probably, but we used to go to a house where the owners had a baby; they and two other sets of parents would go out once a fortnight, leaving us in charge of 3 little babies.
Which actually was fine, there was never any problem, usually they just slept, and we were very responsible and would check on them every 30 minutes, creeping in
But far more important was that the owners of the house had a spaniel, which had puppies
The first time we went, she was pregnant, so then we were there with the 5 puppies at 2 weeks old, etc, for several weeks, oh it was lovely
And yes, they used to leave all sorts of lovely stuff in the fridge, an actual meal in a low oven...and be terribly grateful
