Thanks for your responses! DMB, I have pmed you.

Tan, that's a good idea about putting our names down and seeing how we go. She woke a couple of times overnight and we were able to get her to go back to sleep, in her own bed, without getting her milk.

I wonder if we would actually do anything different if we went? Would they be able to help us stop her from waking, or is she just supposed to learn that herself??
