Safe Sleep

sunny • New

My baby girl is 11 weeks old and I’m constantly worrying about safe sleep. I have no idea what I’m doing. I know back and flat is best but what am I supposed to do about this?? Is she too big for her bassinet already? She was rolling her first few days home from scrunching and is still practicing but doesn’t roll unless we’re doing tummy time. We think she’d still prefer to be swaddled because she sleeps best so we usually leave one arm out if we do. This was last night we tried a footie pj and she just squirmed and stayed up for the longest time. Please be kind this is my first baby but does anyone have advice for the best routine to get into and safest way for her to sleep?
