Tanya, I don't know, neither of my boys would take a dummy. But DS2 is a thumb sucker instead. I would think though that by introducing one at this stage, you might be causing yourself a lot of work down the track for getting rid of it. And I think it is recommended to try and stop dummy usage when the teeth are through.

Maybe you could try a comforter of some sort in her cot? That might work. The other thing is you can try not feeding every second time she wakes and see how that goes. Maybe see if your DH can try settling her instead (it can be much easier without the smell of milk or the site of bbs!). GL hun, I hope it settles soon.
