During the school year, DD9 goes to bed at 8:30 during the week, and I get her up at 6:00. She is very difficult to get out of bed. (She gets to stay up until 9:00 on weekends.) I think she's right on the edge of not getting enough sleep, judging by behavior, but she's often getting up and asking for stuff for an hour or more after bedtime.

DD5 is starting kindergarten tomorrow. He goes to bed at 8:00, and now he will have to get up at 6:00, too. We would think about moving his bedtime earlier, but it will be tough to fit in after work. He's easier to wake up than DD, so I think he's getting a reasonable amount of sleep now.
