Sorry to not be much help but we’ve had numerous episodes of ew and I found nothing really helped. Ours were earlier than yours though at around 5:30. I just tried to help her catch up at nap time or if that wasn’t possible an ebt helped.
We’re on the nap drop train big time now and things seem to have evened out. Our issue now is if we have even the smallest 30 min nap, our bt is epically late, by 1.5 hrs!!
Sorry I digressed, but what I’m trying to say is I think ew are all part of them working towards the final nap drop. I’d read it was a lengthy process for some 🤦♀️😳
