Arrrgghhh what are we to do??

It sounds to me like it's the poos that are waking her as well. Especially as she gets older, it's good for her to be aware of her bodily functions and if she's uncomfortable with poo in her nappy, this might be a good thing for future toilet training! Emma Rose is like this, in that she wakes up screaming if she's done a poo in the middle of the night, and won't go back to sleep until she's changed.

If you can't change her bowel movement habits -- which you might be able to do, by changing what she's eating and when -- then maybe you can just quietly get up, without talking to her, and change her nappy gently and swiftly, and put her back to bed -- again, without any talking or interaction, except maybe just to tell her it's not time to wake up yet. It might take several attempts at this, but hopefully with repetition she'll get the message and might stay in bed or even go back to sleep on her own. It's what I've been doing with Em when she wakes with a poo and then wants to stay up and play, and it took two long weeks of me doing the same thing over and over, but now she will go straight back to sleep after a nappy change.

And your doctor's receptionist sounds like mine -- scary! When we went for Em's pneumococcal vaccine, she was so rude to us that after the vaccine, I asked the nurse if we could just wait in the examination room instead of having to go back to the reception area for the 20 minute post-jab wait. When she asked why, I told her I'm scared of the receptionist, and she admitted that lots of patients say the same thing! LOL
