Ohhh man, $10 sounds really high!
It depends on how many children you have, I guess.
For my three kids when they were younger, I would pay $50 a night. My reasoning was, the kids went to sleep three hours after I left, and she was allowed to go to sleep too. SO, come on! $10 an hour??
Give me a break! That is wayyy too much!!
Edit: If there's an infant that will be waking up during the night, it might be a little different. But, I bet you will be able to find a young mom, or even a retired lady to sit for your children for wayyy less than $10 an hour at night. Or wait, even better,, a teenager,,, someone 16 or so.
