Weird sleeping positions???

My baby is 7 months old and just learned how to sit up from a laying down position. Now when he tries to fall asleep he sits straight up and leans forward and falls asleep with his face sideways on his blanket, he's basically in a taco position lol. I've seen some babies sleep on their tummies with their butt in the air but that's not what he's doing. He Literally sits up, lays forward and falls asleep. Is this ok?? He does it even if I try and lay him down. He seems to be comfortable but idk how that is comfortable at all 😭😭😭
