So sorry about your LO being sick!
How is she feeling? I skimmed quickly but just to add some advice... Since she's been sick, I would just let her sleep, and maybe cap her morning A time having that long night!

30 min naps are clearly OT...! I would def try and sleep or resettle all naps on purpose. When they get sick and OT they need that extra help. At least, mine does! He's a great IS and those times I've had to help, didn't really affect his ability to sleep on his own once it all passed.
I know EBTs scare you... Haha me too! Especially when we don't get 12hr nights often either and DS1 did 5am for YEARS. Haha! But, for now as recovery- I would. My LO recently got OT from our vacations and EBT helped-- he pulled through and did 12 hr nights. Once caught up, that changed haha back to his normal!
Have you tried clearing her nasil canals? With some saline? Or the syringe bulb? That's rough when they use the paci or suck their thumbs. I remember the first time DS1 got sick and woke every 2hrs bc he couldn't breathe

it's so sad! But I had to do a lot of helping... I wouldn't wake from naps or keep all A times the same. I had to reduce one of the A times to recover from OT from this last vacation.
But to answer you, I wouldn't wake or cap anything. She's going to wake nights regardless probably until this passes.

Many hugs and hope she gets well soon!
