I am not deliberately choosing to put my 8 week old on his stomach, but we co-sleep and he sleeps on his side (because he breastfeeds on his side facing me and just stays that way). I often find that he is sleeping on his stomach where he has rolled over. I know this is generally considered an increased risk for SIDS, but I know that co-sleeping and bf all night reduces that risk, so where does the stomach sleeping get factored in?
