DD was very similar to this. She Coslepy with us from birth. Around 6mos or so I think, her sleep deteriorated a lot. We thought perhaps it had something to do with her getting too warm, or DH or I moving when we sleep, and that disturbed her, or something.
So we decided to put the cot up against our bed, and take down the side rail (in effect making an extra section for her to sleep) and that helped a lot! It seemed she liked having her own space but still being right next to us, If that makes sense? She still didn't sleep through the night until about a week ago, but she did sleep for longer periods of time, and I could settle her away from me, but still near me, and I didn't have to get up! lol
