hun, i know exactly how you feel.
DD1 flops around like a fish in bed and i end up with the worst back and hip pain from sleeping around her or waking up to move her etc.

If you can maybe when she comes in walk her back to bed, lay with her for a bit and then go back to your own room, i like Kate's idea of taking her back and then extending the time until WHAM she's slept through.
