I have a friend who lives near Goose Creek, SC (close to Charleston) and she is expecting their first child. The cheapest daycare around her is $1200 a week - and it has a waiting list. She and her husband both work and have recently purchased a small house (2 bedroom) and with their financial commitments they cannot afford to loose an income. The cost of child care is outrageous.
Those kind of numbers put a premium for jobs that allow one parent to work at home.
