m-f the first alarm goes off for my daughter at 6am then i go back to bed until the 2nd alarm goes off for my husband at 7am, but i dont usually sleep for that hour, my motherly intinct has me listening to make sure my daughter didnt go back to sleep. so when he gets up at 7 i try and fall back to sleep for an hour or so. if it actually works sometimes i'll sleep till 9, other than that i just toss and turn till i feel like dragging my self out of bed. same on weekends, when ever i feel like getting up. i feel guilty if i sleep to lage thogh.
just a couple years ago though, before the kids hit highschool, i was up at 7:30 everyday & 8ish on weekends. my sleep cycle is changing guess
