I'm an soon to be self employed lone parent of dd aged 2, I will need two evenings a week and every 2nd saturday child care and have space for someone to live in. My friend who lives a few streets away needs help doing school runs and a couple of other bits for of dc 4&6. Au pair would never have 3 dc at same time as I would continue to use nursery for day time care. Would this work or is it too much?
Theoretically it could work, but there would be a lot of potential for things to go wrong so I think you'd need to have a really tight contract with your friend so you both know exactly what is expected/who is responsible for what etc.
I think her friend could avoid paying minimum wage if she contributes to the au pairs keep. As long as you're providing living arrangements I don't think they have to be in your own house for it to count as a live-in job e.g. where you have a house that you let and the nanny or au pair has a room in it paid for by you.
I could be talking rubbish though so do look into it OP....
