Delicate

So I noticed that my baby hates sleeping on his back now. Also for naps during the day we've been laying him on tummy and he dose good. My baby has good head control that about all and as far as Turing over on his side or back just not there yet. I just put him on his stomach like 15 minutes ago and his sleeping well its still night here. Howevere I'm nervous because laying baby on tummy can be a cause of SIDS. I'm laying here with my hand on his back just to check if he breathing. My baby boy will be one month on Tuesday so is it okay for him to sleep on his tummy and did anyone else babies like this? And should I place him back on his back.
