when i used this with a combination of staying through the jolts and watching the A time (my trouble now!A is out of control!!) it worked pretty well. I would go in at about 20 minutes, jostle. then go back in at 32 and stay with hand on chest and rolled up blanket on legs to keep him from getting worked up, or hopefully even really waking, until sometimes an hour! after a while, well a couple weeks!, i could duck out at minute 47 and MOST of the time we got a decent nap.1:10-1:30. short naps are rough!! HTH.! oh and sometimes staying beyond when i thought he would go back under helped and we would get another 45 min. i didn't find with this method for it to become a prop, until our A's went off the charts he was great at putting himself back to sleep. Nevin has never taken a paci, so don't know there. good luck!!!!
