Flagging this up. I really hope some desperate person doesn't pick this up.
My last house share before I moved out to buy my own place, the live in landlady and her DH had one lovely male tenant who used to babysit/childmind her DC when she had then (after I moved out). He didn't mind doing this (didn't have much of a life outside of work!) but I was a bit
about it considering how much she'd have to pay an actual babysitter, she had lots of family living locally too who helped out with childcare.
