I have 2 kids (8 year old twins) and I generally pay 8-10 per hour. When I ask sitters their rate, I don't get a straight answer. When I had a Nanny, she would charge me $10 per hour for babysitting (beyond our normal day), so that's been the number I tend to use. That was 6 years ago, so her rate may have gone up since then, but I considered her a "professional". I live in the Atlanta suburbs.
