More often than not in the last two months, Andy's been up every 90 minutes or so throughout the night. So its pretty interrupted sleep. I catch a 45 min nap on the afternoon train home every day.
During the week--go to bed by 9:30 usually and up at 5:45am. On the weekends, usually stay up until 10-11:30ish and if I get up with DS, I am up around 7, if its my day to sleep, I get up around 8 or 8:30
