Personally your job is too good to pass up. How much of a pay cut will you take quitting to do home daycare?
My first reaction was you need to hire a full time nanny. one to let the boys sleep in, get them up and off to school they then clean the house, make supper, get the boys from school and do homework with them until you arrive home.
Supper is ready, house is clean, homework is done. The nanny can do groceries and errands as well. I would cost a good chunk of money (perhaps a much as $30,000 for they year) but you would have evenings and weekends free to spend with the family and your boys would have more sleep time, down time and another member of the family (so to speak).
