Up until the last week DD has been sleeping ok at night, bed at 7.30 then she would wake sometime during the night (between midnight and 4am) have a bottle then go back to bed. Sometimes she would go back to sleep in her cot, other times I'd end up bringing her into bed with me just so I would get to go back to sleep.

However she now wakes up as soon as I go to bed, it's uncanny and I don't know how she knows mummy wants to go to sleep now...I've gone to bed at different times the last few nights and without fail every night as soon as I walk into my room or get into bed she starts crying (her cot is in a separate room to ours). I haven't been able to get her back to sleep, I've tried picking her up and resettling and she will fall asleep on me but as soon as I put her back down she starts crying and won't stop until I pick her up again.
Last night I tried giving her a bottle and sitting up for a little while with her but she still ended up in bed with us. It seems that nothing but being close to me will get her to go back to sleep.
I wouldn't mind except that DF doesn't like her being in bed with us, and while I don't mind it every so often, every night is starting to get to me. It's not that comfortable for me after a while because the arm I'm lying on goes dead and I can't roll over, she starts squirming around at 5/6am and while she is still asleep I'm awake because she is wriggling around so much. I don't sleep as well either because I'm still tuned into her movements to make sure she doesn't roll off the edge of the bed.

I don't know what to do...
