Anyone else's baby rolling to tummy then trying to nurse?

My son keeps rolling onto his tummy when we're side lying nursing and trying to nurse that way but his nose gets covered so he can only nurse for a second before having to pick his head up and try again...at first I thought he was accidentally rolling and would turn him back to his side but he'd get mad and roll again...then I thought he was just rolling for fun and I was in his way, so I started scooting backwards but he'd shuffle toward me and root around to nurse. He doesn't sleep on his tummy or anything. Anyone else's baby doing this?
