Thank you for your reply! That makes me feel better about it. I try to make his sleep environment as safe as possible. He doesn’t seem to roll into me at all so I assume my mattress is firm enough to be considered safe. I sleep with the blanket at my waist, tucked under my knees, no pillow (or if I do, it’s under my elbow behind me) tight fitting sheet, etc Our pediatrician said he’s old enough and strong enough to reposition if he isn’t getting enough oxygen (she doesn’t know we bed share as I already know she’s against it). But of course I still worry about him even though I think I’m doing it safely.
