Wow, I can't believe how many people wake up around 6 naturally!
I am not a morning person. My dp wakes at 6:15 and I wake up a little with him but usually try to go back to sleep. I've also had some insomnia rearing up lately, and I have a hard time getting to sleep when I'd like to do so (around 10 but usually up til 1ish or even later, I know, bad!), so I don't feel bad about getting every wink that I can in. I'm growing a human, now, and I need my baby sleep.
Anyways, M-F our roommate gets up around 8 and that usually wakes up my dd (who otherwise will sleep in til closer to 9 which I LOVE), and then she comes down to use the bathroom, and I'm awake after that, stay in bed snoozing or cuddling up til 9 sometimes. Somehow she has hardwired herself to wake up at the crack of dawn on Saturdays to take maximum advantage of Sat AM cartoons, to my chagrin. So those days she'll creep down really early and turn the tube on very quietly and sit there and screen out til me and dp get up---which I really dislike, ugh. She is very addictive about it, and then cranky for the rest of the day, sorry OT.
We eat brek immediately after getting out of bed, so I don't feel bad about that either. On weekends, my dp will languish in bed (which means we all do, too, for team family cuddle factor), and sometimes we'll stay in bed til we're all low on blood sugar and cranky, and that's bad for everyone. So I try and be aware of that and be the first one up on weekends---still not unusual for us all to stay in bed til 10.
I guess . . . if there's no reason to wear day clothes, then why stress staying in pajamas? DD usually wears yoga pants and a tank to bed instead of "pajamas", though. But really, I don't care if she wants to wear her pjs for days. Wear em to the store if you want to. I'm really glad that she's not in school and we don't have that pressure of being fed, showered, dressed to a T, and ready to roll before 8am. That was horrible last year! My family has a really hard time getting out of the house before 10.
