How much extra do you charge for more than 9 hours? When I interviewed this family I told them it is a max of 9.5 hours per day, and somehow they are here for 9.75 hours per day. If I were to do it again, I would make sure the client falls between the hours of 7:30am - 5pm. Like I said, I can see myself replacing them eventually because I can only do such long, early hours for so long.
