Anyone know?

I'm going to ask our pediatrician at our first appointment tomorrow but until then I'm watching him like a hawk. 
Our little guy is 4 days old now (old man!) and I put him on his back to sleep but he turns himself to his side to face us. The SIDS recommendations say baby should be on his back for safest position. 
What to do? Should I just keep turning him back on his back or what? 
FTM here...so many questions!! Anyone else come across this? What did your doc say?
