Bek - for what it's worth, I have been just taking my temp when I wake up. So long as it's not 3am (I would hope I'd get another few hours sleep if I have to get up to Gabby at that time!), I just take my temp whenever. Usually it's within the same couple of hours (usually between 6-8am.... for some reason I wake at 6:20am most of the time!). My charts still seem to be working (I got an O time and a coverline last cycle without too much hassle). I know with little ones it's hard to get the temping exactly right because there's so many interruptions. I refuse to wake up to an alarm if I'm not working so I just do it when I wake. I'm just too selfish with my sleep these days, LOL. I know it's not the right thing to do but it's working for me!
