Hugs Kara, It looks like she has some major OT built up. Could you shorten her day a bit to 10.5 hours? That may keep her from getting so OT, or will she not tack on at night? M went through this for awhile where his short nap would shorten his nights then the next day he was tired but still didnt want to nap, so we did sebt after 10 hour day. Then there was the point when after 3 days with nn his night was getting super short so we did ebt after a 9.5 hour day. It took awhile but he got it all straightened out without too much fuss.
I am amazed at how many are doing nn 12 hour days, M has always been low nap needs and very high A time needs, but he is only doing 10.5 hour days from wu to put down, closer to 11- 11.5 hours from wu to sleeping.
