I did this for 6 months before circumstances changed and I had to let it go. There's a lot of regulations, and STACKS of paperwork. The best part was the kids, the worst part was feeling like your house was never yours (I had to put up posters about handwashing/sleeping/fire escape stuff everywhere) the house looked like a workplace, which i guess was the point. It was brilliant making cookies on a monday afternoon with excited kids and thinking ''I'm at work!"
