Just reading this now. Sounds like our evening last night. Wayyyyy OVERTIRED - that was DD, me and DH.
I'd been out during the day and dragged her in and out of the car, oh at least once at the shops and then back at home again. It threw her sleeps out completely and she hardly slept yesterday afternoon and was screaming on and off, whilst being held, rocked and shhh'ed by us. OMG, thought she'd never go to sleep, all the while, we were trying to watch and hear Downton Abbey.

Sleep school with DS1 said that there's only a small window of opportunity to get tired bubs into bed and asleep and if you miss it and they get super tired, it's nearly impossible to get them to sleep easily. And then they wake more and it's on again! Just keep an eye out for jerky arms/legs, looking away/no eye contact, fists and get them into bed pronto. Yawns and crying are late tired cues and I find that DD won't settle too well if she's at that stage.
Hopefully Miss A is back to her normal self!
