If I've had a rough night I will give DD2 to DH and go back to bed but I can rarely sleep past 8am these days.
Pre-children I would happily sleep until 9 or 10am if I wasn't working an early shift.
I find this interesting. It shows that night owls are born , not made.
I would describe myself as a morning lark, because i love nothing better than the beautiful energy i get when i first wake, and there is something special about those first hours. HOWEVER, i still think its unnatural to wake pre dawn, and that is what between 6-7 is nowadays. Ie, i wake up considerably earlier than i used to, but even then, i would wake at 8 or 9, and still considered myself a morning person. I went out in the evenings though, and sometimes got home late. I also worked late shifts at one stage-i still preferred the morning then, but that was watching the sunrise after a nights work! Then i felt like absolute crap the following afternoon,only to regain my well being by about sunset-welcome night owl!
If I get to sleep in until 7 I am beyond thrilled! We live on the border of Canada, so in the summer it gets light before 5 and in the winter it's still darkish at around 8. My kids wake up at around 5:30 - 6:00 every morning, regardless of the sun being out or not. Drives me nuts, because no matter how quiet they are, they wake the baby up - who, like me, is a natural night owl. :)
We don't have to be up that early. My son's school bus doesn't pick him up until after 8, and they don't take a long time getting ready for school. But they like to get up and play in their rooms or read.
