Glad she managed to get to sleep at a reasonable time.
FWIW I always try for either EBT or regular BT and just tell myself to expect the worst, to be prepared to "give up" on BT if there is huge resistance (and try again 30 min later or so) or prepare myself for NWs either from OT or UT due to some mega nap from the illness or because of coughing/snot etc. I tend to feel okay about things once I've prepared myself for a bad night and then it usually turns out better than I thought.
Hope the night went ok and you all got a bit of sleep x
