first of all big hugs You didn't have the start you wanted, but it sounds like your milk has come in really well. Paige wants to be close to you, which is normal, and feeding a lot is also normal as she gets used to life outside the womb.

That said, feeding from midnight to 7am is most likely for comfort rather than solely for nutrition, and I wonder if she has a sore tummy and is using you because of that. She sounds exactly like my DS2 and it took a while to get used to the fact that even breastfed babies get wind sometimes and need burping. After a feed try lying her over your knees with her head slightly lower than her tummy, and rub her back (for maybe 15 seconds) then lift her upright and pat her back upwards. That should bring up any wind that is giving her a sore tummy.

If she has another night when she is awake all night, at some point in the night go and wake your OH and get him to take her for a couple of hours (even for a walk in the pram or just around the living room) whilst you get some rest. I know it is hard to wake someone else when only you can breastfeed her, but she will be ok for a couple of hours without milk if she has been feeding non stop, and the rest is important for you. If you find a dummy helps her then it will be ok to use one, as long as you are not giving her a dummy instead of a feed. It sounds like you are doing a great job though, I hope you have managed to get some rest whilst she has been sleeping.
