Enjoy it. Seriously. Sounds mental but try to think of it as your own special time. (I told a mum at DS's school today that I enjoyed the night feed with my 29week old, she thought I was mad)Do a dream feed before you go to bed and you might only be woken properly once. How is she napping in the day?
It's the sleepless nights of DS1 that we look back at and smile about now, but at the time it was awful. DS2 had only given us 2 sleepless nights since he was born 5mths ago, but I am well aware that that could change all too soon. skin to skin, lights off maybe? when i say skin to skin, just un-popper her sleepsuit at the front so when you put her down you can do them up without disturbing her too much.
