I know this is late and you've already decided what to do, but it really does seem like you'll have to roll with it. She does sound in an awful lot of pain and very tired. Now, you know I'm in a bind with the AP I've done, but in your case, she REALLY probably needs the help. So, offer what you feel comfortable with and try to get her the sleep she needs. I'd say if she's falling asleep in those weird places, she needs the comfort and is really exhausted. Poor little girl, that's a lot to be going through! And you must be so tired too. Sending lots of (((hugs)))!
Also meant to add, a 1 hr nap is usually OT here, that could be what happened yesterday.
