@chenml60 Of course it’s still safer to bedshare than to fall asleep on the couch even if you formula feed. If you can only do 6/7 that’s okay. One benefit to breastfeeding is that it keeps mom from falling into a deep sleep next to baby. (Which also has its downsides, I usually need an extra half hour of baby free sleep somewhere.
I would just try to find another way to mitigate risk. Can you side car a crib? How firm is your mattress? Maybe upgrading/downgrading to a super firm mattress. Or moving to a floor bed.
I personally use a twin size crochet blanket that I drape mostly behind my back. I feel more comfortable using a crochet blanket because the holes feel more breathable. You could also get one of those zip up house robes.
If you’ve woken up with your arm on top of babies face I would be trying to think of ways to prevent that. If babies sleeping closer to your face I would try to not use a pillow, or use a very small pillow, and make sure there’s no space at the top of the mattress where baby could slip into the bed frame.
