I have an Au pair and we are currently hosting our 9th one! It is flexible and affordable compared to daycare and nannies! I pay about $340 a week for 45 hours. It's live in and they become like family ! It's one of the most amazing things I've done and all of my Au pairs cook a family dinner and get kids homework done. If my kids are sick at school and I cannot leave work she picks them up! I never have to worry about school vacation days either!
