I used to get paid per night. One girl I babysat I only used to look after for a few hours and I got $20 for the night. Another group of people I babysat for paid me $10 an hour and there were a few more that were a bit higher. If you feel bad not paying her and she says she doesnt want money why don't you buy her a voucher for a cd store or something like that after she has babysat a few times?
