Ok, that's different, sorry I misunderstood. I have a full time rate and a part time rate. My part time rate is $2 more per day and my contract states a minimum of 3 days per week. I do enjoy having a few slower days so it's not a problem for me to have one client who uses 3 days/week. In Ontario we are only allowed to have 5 children max, so it sounds like you are working hard.
