Would an older lady do that for that amount of money? Yes, and I know lots of people that would probably do it for free. They would probably love to come over and spend all day with a baby. I'm sure she's not in it for the money. OP if you can afford to pay $10/hour go for it. I"m just saying that would never happen around here...unless you were somebody rich.
Well, judging from all of the other posts, paying $10+ an hour happens almost everywhere else.
