My three year old has a big ole fancy bed, with a slide and everything. And he still will not sleep in it. He was so excited about his big boy bed and helped us pick everything out, yet he is still not interested in sleeping in it. He has co-slept with me for a few years, until recently. I had a baby 5 weeks ago and I have to tell you that a screaming baby in the middle of the night has cured him of sleeping with me. However he still sleeps in the guest bed. I know it is so weird. My husband works the night shift so I am alone and it is not a big deal. I figure it is not hurting anything if he wants to sleep with us. If you really want to move him out you just have to be diligent and have patience. Move him back to his bed eachtime he gets up with you. Dont make a big production out of it, just take him back there. Have a nighttime routine that includes his bed, like special story time in his bed or something. I did all this before with our son and it worked, but while I was pregnant I got lazy. Then I was on bedrest and it was just easier to have him back in there.
I found that it was actually easier to get him to sleep in his own bed once I started working on it. At first he would fall asleep in there and then show up in my room. Then he would be moved three or four times a night. It slowly dwindled till he slept all night in his room. But like I said I got lazy, the first time you let them come back it all falls apart!
Oh and I also talked to him about his room. Finding out if there was something he was afraid of, or something that he did not like about his bed. He was worried about the tent area underneath, so I made monster spray in a spray bottle and we took care of them! LOL Also we set up some of his bigger stuffed animals in there to protect him at night. Then we hung a couple of pictures of me, my husband and my sons grandparents around. It seemed to help.
