Xander won't sleep without me!

I'm creating a monster! Xander doesn't want to sleep without me. He only sleeps for short periods of time (fifteen to twenty minutes) if I'm not with him. I hate to let him "cry it out" but I'm wondering what kind of habits I'm creating for my kids. Brandon is still sucking on his "bubba" and sleeping in our bed and he's two now. I got a lot more done today, but not as much as I would have liked and we still haven't worked on our "schedule." Oh well, tomorrow is another day.
