We also had problems putting dd to bed for a while. For your situation I would suggest that you try to not pick her up, instead try and settle her in her bed. It may be a bit of separation anxiety, which will pass.
We spent a lot of time in dd's room waiting for her to go to sleep (trying to leave before she went to sleep which sometimes worked, sometimes didn't!) but eventually got to the point where we could put her down and leave, and she would cry for a very short time, but not like she needed us, more like just a tired cry. Now she is pretty much consistently back to going to bed without any protesting.
