I think if I were having difficulty filling my spaces, I would consider extended hours for an extra fee, but most providers I know have even shorter hours than me (I work 7:30-5:30). I understand your frustration, but you have to remember that we work very long hours and are not paid hourly and most of us do have our own families to care for as well. Maybe some of those providers who list their hours as 7am might be willing to negotiate an earlier start time for you for an extra fee if you contact them. Good luck!
