okay, my fiance goes to work at 10 pm. He gets off at 6 am. Our son falls asleep around 11 pm. I stay up from 11 pm to 6 am because that's the ONLY time I get to myself. Yeah, I am REALLY sleepy but it's the only time I have. I cherish it.
my husband works from 4pm till 2am. so i normally stay up till 2 or 3. then get the kids up at 7 to go to school.
