K.,
I agree with Susana. I have a 3 year old son as well and he still wants to sleep with me also. I have tried everything, and I found that the only way that I can get a good night sleep is by letting him fall asleep in my bed and after he is asleep I take him to his bed. I also let him sleep with his brothers which also helps. If you have other children you should try letting fall asleep with them. It's probably that he just needs to feel somebody next to him. Once I did that he did just fine. I mean at times he still gets up in the middle of the night and climbs into bed with me, but the magority of the time he stays in his room. You should try that and let me know how that works out for you.
