He has turned you into his security blankie and just like the bottle and the pacifier he can be weened off of you too. My son did the same thing. He started out sleeping with me due to a reflux like problem (pyloric stenosis)he had for the first seven weeks of his life. After he had surgery to correct the problem we played havoc trying to get him adjusted to his own room and bed. I finally started laying him in his crib awake and would rub his tummy or his head untill he fell asleep. I kept that up for a couple of weeks, then I would just sit in the rocker at his bedside untill he fell asleep. Each night I would move the rocking chair a little closer to the door untill he finally got used to me being further away from him. Another thing to remember, don't make direct eye contact with them or speak, all children regard eye contact as part of their communication with you. Try to keep yourself quiet and calm. It took us some time, but my reward was having my rest back.
Hope this helps you out!!
