I am reopening, and new hours are 6:30-4:30. Used to be 7:30-5:30. I am switching to conform more to our family's schedule and the kids' extracurricular activities. I was a little concerned that I wouldn't have any interest, but I actually think I have just tapped a different "market" of parents than I had before. I WILL NOT work for more than 10 hours though. I don't think people realize that in home daycare, there are no breaks! I can't pop out for a coffee with my co-workers, or take a nice quiet lunch break.
I made the mistake of doing the "early start" for one family a couple years ago. What do you know, they started showing up earlier and earlier, and picking up later and later. Never again.
I will admit that I am loathing the idea of getting up at 5:45, though.
