Washington DC burbs, so HCOL, but not NYC prices.
Before younger DD was in elementary school, we paid $1150 a month for full time care (7:30 AM - 6 PM). Infant care was $1450 at the time, toddler care was $1350.
Until this year my kids went to after care and I paid $350 a month per kid.
This summer I had a college nanny and she charged me $100/day for up to 10 hours of care. I am now paying her $100 a week for after care for younger DD. As a side benefit, she's also home for older DD too although she doesn't need "care". She's here from 3:15 - 5:30, 4 days a week. (I telework one day a week.)
