Re: Why is she still waking up so much during the night?
In my experience, it is very unusual for a co-sleeping, breastfed infant or toddler to NOT wake (or partially wake) every 1-3 hours to nurse.
If you think yours, and the other bed occupants', movements are waking her, perhaps you could try putting her in a side-by-side type crib -- like the Arms Reach Co-sleeper, or any crib with one rail removed so that the mattress is more or less level with your bed, or better still, as many mattresses as you need on the floor so that there's room for everyone! That way she is right beside you, and you can either pull her over to you to nurse, or scoot over to her, and then back when she is asleep again, but she won't feel every little movement on the mattress you (and everyone else) sleeps on.

Those who say it can't be done should not interrupt the person doing it.
