D..
Ephie, when my kids were little, it was organize, organize, organize. (Not my closets, mind you!) My kids' rooms were organized so well that I knew exactly where everything was. My diaper bag was filled all the time with what I needed, and when the kids were bigger, a tote bag. I had snacks, wipes, water, extra clothes, plastic bags in case of an accident, etc. I had all the doctor/dentist etc numbers written in case of emergencies and at my fingertips. We cooked on the weekend and then just worked around those dishes when we got home from work.
I'd wash one or two loads a day and not miss a day so that my weekends didn't blow up into a truckload of laundry to wash. There was a little bit of time after dinner to clean up, but mostly I used it to play with the kids and get them upstairs and started on the evening routine. My husband and I worked together to handle the kids - baths, teeth brushing, reading books, gentle playing, and then bedtime. I never had to be on my own with it because my husband loved being with our kids.
Then we'd clean up the kitchen - ugh! When I became a SAHM later, I had trouble balancing fulltime responsibility with being covered up with my kids and finding out who I was, since I didn't have my career anymore. That was hard, I'll tell you.
It's easier now that my children are mostly grown. I don't worry about organize, organize, organize anymore. (Maybe that's a bad thing...LOL!) But I suggest you do that and write lists, because it will give you more time with your family and help you not be stressed as much while you are at school.
That's how I did the balancing thing.
Hope this helps!!!
