Baby sleeping on stomach

My son is 5 months old now and he keeps rolling over on his stomach when he sleeps. From 3 months to now he liked to sleep on his side but now that he just recently learned how to roll over onto his stomach, he’s been trying to do that in his crib. As a ftm this scares me because you hear about the risk of sids and everything but for other moms options, is this ok for him to do this? Should I just let him sleep on his stomach if that’s what he wants to do? He keeps his face to the side for the most part. But with him just now learning how to roll over he has been struggling a bit on flipping back on his back.
