I work in child care and I am thinking I might do this in the future too cause I don't wnat to work outside of the home either.
I'm thinking I'll look into just nannying though cause then you don't have to go through all the family day care inspections and paperwork and you can set your own rate.
I think it would be tiring and I'd probably just to 2-3 days a week so you had 'alone time' with your own children too.
