Your schedule sounds similar to what I used to deal with for many years.
We had 5 children.
My husband worked 2nd shift. I would wake around 6am and get the kids up, fed, ready for school. (They attended parochial school with the church we were part of.) I worked as a HS teacher assistant, Art teacher, and PE/recess duty. I went home early around noon to get my husband (who was just waking up) fed and feed my youngest ...got hubby's supper made (to take to work) and saw him off to work by 2:15pm ....then headed back to the school with my little one in tow, to pick up the other 4. We came home ....got homework done, housework/chores, supper ....kids to bed ....hubby home at 1am and I was usually still awake. Goodness, I kept that schedule for years. It can wear on you!
