It sounds like she is going through that seperation anxiety stage, Xander started at 9mth. The best advice is to go with it. Let them know where you are at all times, lots of cuddles. Xander used to drive me nuts as he would want to be on my lap then on the floor, then on my lap then on the floor but if you just relax and go with it they get over it much sooner. We coslept with Xander and had no probs getting him in his own bed. We always put him down in his own bed and brought him in to us if he woke during the night.
