I'm SORRY this is long but I really need help
My sleep is totally irregular. Even if baby sleeps through the night, it is not uncommon for me to wake up anyway although I go quickly back to sleep but I have 2 that are inclined to wake through the night for various reasons so my goal with temping has been to try to get a reading after 3 hours of straight sleep which is tricky in itself but I've been doing decently, it's just that the time I actually take my temp at has been totally random this month (last month it seemed to always be 3:30 or 5:30 instead of total randomness).
Since I temp before looking at the clock since seeing the clock takes more effort than I'm supposed to exert before temping, I sometimes end up with a couple of readings through the night (I might find out when I do check the time that it's only been an hour since I went to bed so I'll temp when I wake the next time, for instance) and this has made me aware of much my temp changes through the night and totally confused me about which temp I should use.
For instance: Say if I went to sleep at 11, woke and temped at 1 [not enough sleep], then again at 2:30 [enough sleep if you ignore waking and temping and I have a few temp readings at this time already on my chart] and then again at 5:30 [after a solid 3 hours of sleep but only a couple of readings at this time on my chart] I'm left wondering if I should record the 2:30 because of more consistent time or the 5:30 because of more consistent sleep

). Is this confusing?
So .. there's my question. Until I can do both consistent time AND after 3 hours of sleep, would it be better for me to aim at a particular time and just note on the chart if I hadn't had enough sleep that night or should I continue just recording temps taken after 3 hours of sleep regardless of when they were taken?
For anyone who read all that and responds, THANK-YOU!
