Hm. Weekdays, I *should* be up by 6:30am in order to get my daughter to her school (we leave at 7am, or *should*!) but lately, I've been staying up too late, and find myself waking up at 7am. Oops. I know it sounds funny as hell, but the birds this year around our house are so LOUD. I mean, LOUD-loud. THey've woken me up at 2am two or three times already! I have rotten sleep patterns anyway, after 15 years of children waking me up between 2-4am, I've just about given up on staying 'normal' for any length of time.
On the weekends I tend to wake up at the same time, esp when it's sunnier in the morning. I love waking up to sun. But if I don't get my 7 hours straight through, I end up falling asleep for a couple of hours the next day-morning or early evening.
