Bedsharing safely is what is important in this discussion. Sleeping how you normally would but with a baby is not safe, sleeping on a couch or recliner propping your baby with pillow is not safe, swaddling you baby in your bed is not safe, baby sleeping on a dock a tot in a bed is not safe. There are so many reasons that can make bedsharing unsafe that it just isn’t recommended to do at all. Your baby is safest either alone in a crib or bassinet without anything but a swaddle or sleeping sack or safely bedsharing fallowing all bedsharing rules (google safe saves of bedsharing for best and clearest guidelines for safe bed sharing)

Depends on how you define it. Same bedroom different bed is the safest. It isn’t safe for a newborn to share a bed with you, it increases the risk of SIDS.
