Hi N.,
Let me preface this by saying that our son always slept in his own room, so I don't have personal experience with this, but I know many people who have successfully dealt with the same issue. A quick note about the Nanny TV show reference; my brother actually worked on Supernanny (there was also Nanny 911, or something like that), and he knows Jo, the nanny who visits the families. Apparently, she is very, very good -- for real. Her methods are quite effective. Of course she is on a TV show, and you can't take everything at face value, but my brother did say that her methods are amazing and work very well. I have one friend who did what another poster suggested, which is put her daughter (who was almost 18mos) in her own crib in mom and dad's room. Each couple of nights they would scoot the crib a few inches further away from mom and dad's bed. At one point, the crib was right in the doorway. Then it was in the hall and finally in her daughter's room. It took two or three weeks, I think, but it worked. My cousin's son would start in his own room (I'm not remembering what age he was, though I think he was at least 2) but would always come into his parents' room during the night. They actually had to put up a gate in his doorway (that he couldn't open or climb over) and just let him scream for a few nights. He got the picture and eventually gave up, but it was heart wrenching for his parents. Personally, I would try one of the other methods first!
