Take breaks from what? Schooling the kids? Or just everything? I take breaks from schooling the kids and I usually do household chores, check my email, etc.
I also take a "lunch break" for about 45 minutes where I do whatever I want. Usually it is veg out in front of the computer, editing photos, reading blogs, coming to this board, etc. Occasionally I will read a book during this time. I have my lunch after the kids are finished with theirs so that I can have this time for myself and they can go play.
