Teething can be very hard on the little ones. I don't think there's much you can do until they are comfortable again - trying to force changes now probably won't work.
Are you open to co=sleeping? That's how I survived when DS was teething. He was in so much discomfort he coudl hardly sleep at all. Sleeping with him didn't change that, but it made it a bit easier on me (didn't have to get up). Otherwise, just try to work around it = get lots of help at home and try to nap when she does, or have a lie in on the weekends and things like that.

Feeding can also be uncomfortable when their mouths are sore.
