My dh and I team tag. During the school year, I leave the house at noon and get home at about 8:30 or 9:00 PM on Mondays, Wednesdays and Thursdays. Those are my slow weeks. During my busy weeks, I'm gone from noon - midnight, Monday - Friday.
Dh works from home on the days that I'm working. He helps the kids finish whatever schoolwork is left over from the morning. He gets his "out and about" work done on the days that I'm home.
When I have to leave at noon, we're pretty good at getting schoolwork done in a timely fashion. When I'm home all day, it seems to stretch out forever!
We have one evening where our work overlaps every week. We had a babysitter, but she found a job with more hours. Lately, our kids have just been going to that meeting with dh. It has worked pretty well, and it saves us some money.
