Another dayhome lady I know does this and loves it. She has tried both full-time and part-time and a combination of both. She finds having the extra day to do chores, hanging out with her own kids or a chance to go away for a long weekend.

I have thought of changing to 4 days a week, too, but all my families are full-time and I love them all. So, I guess I will need to wait until their kids get older and don't need me anymore.
