Well, it wasn't too bad after all!
Took LO to bed around 7 and fed her. Put her down drowsy and she started grizzling so I decided to start the checking at 2 mins, then 5, 10 and 15. I stayed in the room the whole time but she couldn't see me, I thought opening and closing the door too much would disturb her even more, and I could hear what noises she was making better if I was in the room.
Here are my notes on what happened:

So really she slept from 7:30-11:30, 1-3:30, 3:40-5:40, 5:50-6:50. Her usual wake up times are around 11, 1, 3 and 5 anyway!
And the best thing? No night feeds!!!!
I've thought for ages now that she doesn't really need the night feeds as they were so short, but as she doesn't take a bottle I couldn't easily swap BF for EBM or reduce the amount she had. So I decided last night that if she was truly hungry, her whinging would turn to crying. But she never cried once - just her whingey, moany noise 'un-ner' over and over, so it wasn't distressing in the slightest.
It took an hour and a half for her to get back to sleep from 11:30-1 (which was when I posted saying it was awful, I thought it was going to carry on all night!) But overall, I'm happy with how it went. I don't think at any point LO was distressed, just unhappy that she wasn't having her usual booby & cuddles to get back to sleep
