I work full time (between 40-50 hrs/week) and have 3 kids in elementary. Commute is about 25 minutes in pre-rush AM and 30-35 minutes in PM.
Wake up at 4.
Do a few things at home/light clean up.
Gym (in my office building) at 5-5:30
Work at 7
Leave work at 4:30 or 5 (4:30 if I need to stop at the grocery store/gas station; a little later if there's something I need to finish at work)
Pick up kids from aftercare 5:45
6-6:30 Let them watch tv while I make dinner. Throw in a load of laundry.
Eat dinner with kids (DH and an older kid may or may not be there if there is a sports practice pickup)
7-9: clean up after dinner, get lunches ready for next day, help with homework, fold & put away laundry, yell at kids to get ready for bed
9:30: usually they're asleep by now and I get my own stuff (work and workout clothes) ready for the next day. Try to do some reading/internet surfing. A little work if I have to. I don't watch tv anymore
10:30: usually I'm asleep by this time.
