try to put him down w/o it occasionally. Start with a day his is super tired so he'll sleep sooner... if he cries a bit, let him and do like you do with sleep training ... (if he cries hysterically, then just let him have it!) You can also put him down early before he is very tired for a nap and leave the paci in the corner of the crib, lay him down and let him figure out how to fall asleep.
If your bedroom is just down the hall, close his bedroom door and if his cries are quiet they won't bother you so much (quiet cries are okay and normal for a baby falling asleep and going through sleep cycles), and if he really needs you you will hear his louder cry through the door and you can get up then... (no baby monitor needed)
Good luck on your precious sleep!
