I do not charge for days that I do not provide care due to family/own illness or appointments for self/family. If I provide care for just part of a day, then have an appointment in the morning or afternoon, creating a shorter day, what should I charge? I usually charge $40 full-day. Should I say something like $25 for under 6 hours (or something like that), or break my $40 9-hour day to an hourly rate, then charge for however many hours I provide care? Other options?
