I'm really hoping I'm not creating a habit or going backwards here

I truly believe that my LO is just not feeling well and that's what I need to focus on for now.
In order to do that while horribly sleep deprived (for months) I need a little reassurance or a success story!
6mo - PU/PD sleep training (dropped paci, NF and swaddle) - rough 9 days but it worked. 6 weeks of blissful 11 hr STTN
9mo - crawling - sleep haywire
and it's continued.
finally 2-1 transitioned about 6 weeks ago and she was doing much better with day - 2 x 30m naps moved to 1 x 1.5h nap (good for her!) + better night sleep.
I think we got through the 2-1 barely and then she got her first cold. But we were not 100% with the 2-1 and she's still not been STTN more than 2 x week at that point.
She's rarely sleeping past 5:30a which makes for a loooong day with only 1 nap. Esp since her overall night sleep is ~8 hours

horrible.
She's usually pretty happy during the day surprisingly. She's lower sleep needs, but she does need 12 hours total according to the pediatrician.
She will not nap (one time only hit 2 hours) longer than 1.5 hours during the day.
Used to do 11 hours at night.
So... now:
5-6am WU (was 6:30a)
9:30a (ish - before 10a) CN capped at 20 min
12:30a set nap (1-1.10h atm)

6:45p BT (we try bt 6:30-7p)
NW:
~11-1a (usually 40min -1.5hr)
2-4a (usually this is the one that's for 2+ hours!)
5am EW
We're back and forth with cot parties for 2+ hours between 1am - 5am.
CN in the am, sometimes while nursing. Overall not good sleep for anyone. I'm the weird BF mom that cannot no matter how hard I try get her unlatched when she's asleep! She latches harder with teeth - ouch!

It's definitely time to wean after cold and holidays. We'll go slowly - one thing at a time.
At least she's never nursed to sleep for her set nap or nighttime or in the night with NW.
I wait until after 5:30a (usually 6am or later) to nurse her.
There's still quite a bit of snot going on so hopefully this is cold related.
Wondering if anyone has run into these crazy cot parties and EW and what got better?
I'm hoping this is a phase and letting her sleep on me after 5am isnt' creating a bad habit.

I do pd / toddler, standing in crib, offer water, no talking in the dark from her sippy or ibuprofen/acetaminophen if she's sounding super uncomfy from teething/cold. I do this until 5am when I try to make sure it's worked for at least a few mins leave the room and if she unsettles and stands back up crying I abort and take her with me to the daybed in the room and cuddle/try to get her to sleep on me to save a little of her day! Usually works. She CN for ~40 min usually.
She's just not 100% well and I want to be there to comfort her, but not after she's well. Anyone have similar APOP while sick experience?
