Same with Rowan- face at boob level, pillow above my shoulder. I cover up his legs with my blanket too, but as he gets bigger that might change. Now that he's grabbing things I've changed the bed around so there isnt any loose fabric (pillowcases) to grab above his head and the side pillow has a blanket over it that is tucked in tight so he can't get it. He sleeps pretty much touching me all night and I think that's why he rolls over when I get up.
Most of the night I have my arm across his hip so he doesn't kick and fuss around. Like a human swaddle. If he's not touching me he wakes up pretty quick. His part of the bed is a lambskin, so it's kind of fluffy, that's why I have the to flip or not to flip question. I think I'm going to keep rolling him back to his side until he gets better at not pinning his arm down
we pretty much sleep the same way...i'd keep rolling to the side until he's good at rolling in both directions...but that's just me. i'm pretty much belly to belly and prefer it that way until they are ready to be far. it's somehow reassuring to me that all is well--and so i don't worry.
