My 2 month old refuses to sleep on his back. Any advice?

I tried tricking him into sleeping on his back by letting him sleeping in my arms for 20-30 mins before laying him down. He'll sleep for a max of 2 hours before realizing he's on his back and wake up screaming. I've tried everything- swing/carseat/boppy, placing him on his side with a towel or blanket infront and behind him, I even bought a foam to make him feel snug, and giving him a little cereal. He rolled over at 2 days old and again at a week old and hasn't stopped since. I think placing the blankets and foam makes him feel restricted. I can place him on his back oneway only to find him facing the oppisite way when I check on him. I even found him in the corner of the bed on his stomach with one arm hanging off. When he's on his stomach I roll him back over onto his back only to him awaking up screaming, refusing to go back to sleep no matter how tired he is. I've read all the articles on SIDs and done the research. Is there anything I haven't tried that may work? Help
