I think it depends where you are looking in the Richmond area.
I looked at 3 daycares within the city, and their rates ranged for infants from 240-290 per week. I know a well-known daycare on the west end that currently costs 300/week! And, I have a friend who priced daycares on the southside and she said they ranged from about 200-280/week. The price goes down a little as the child gets older.
My experience has been that if you find someone who cares for multiple children in their home, it costs about $120-200 a week.
