I would try swaddling tight anytime he sleeps. That's what we had to do. If he is getting out of the swaddle easily, there is a swaddle blanket called the "Miracle Blanket" taht is supposed to be just awesome. We haven't gotten to that yet, because i have been able to really swaddle tight. My ds is a major thrasher. If he isn't swaddled he is awake as am I. I have also found that during hte day if I put him in his infant car seat to sleep, he goes right out. Just a thought. HTH.
