One of the daycares in our area offered New Years Eve care, 10PM till 10AM and she charged $100 per child. She told everyone that she needed at least 3 children -6 yr to 10 yr-- to make it worth her while. She offered a few games, snacks and breakfast. She did very well. I think my husband would divorce me if I offered to take the daycare children any more days than I am (5 days per week--7AM till 5:30PM)

Good Luck.
