I agree with Brenda. Talk to the parents and see what they think. I have a neighbor who is extremely opposed to anyone "paying" her kids to do things. She would rather trade for something they like or some kind of treat. My other neighbor doesn't mind having her son be paid money, but doesn't want it to be a very large amount for anything (he is 9). Before reading your responses, I was thinking if it were me, and I just wanted to pay money instead of come up with some other kind of compensation, I would probably give the boy $10 when I got back. That's roughly $1 per time he comes, plus a little extra for making him rearrange, or keep to, a schedule for two weeks.
