Lately, however, there's been some bedsharing as well. Waking every two hours to feed her was a bit of a drag and moreover, felt unsafe as I couldn't stay awake once I had her on the nursing pillow in bed with me. If she's on the bed surface to start, she's not going to roll there and land face down or, worse, roll off onto the floor.
I'd prefer to get her back in the crib, but so every so often, she ends up in bed, and routinely ends up there after her 5 or 6am waking since there's just some dozing to be done between then and work.
The above linked article is pretty interesting and worth a read. I especially like this part which academically chuckles over the paradox created by our cultures relationship with its ethics rules
It remains a curiosity of western cultures that we are largely unable to study prolonged mother-infant separation in a laboratory setting, even though our culture in the US provides us the perfect “natural experiment,” with thousands of neonates and infants being left to sleep alone for long periods of time every night. However, it is reasonable to at least suggest that solitary infant sleep represents an evolutionarily anomalous setting for human babies. As a result, infants may experience a physiological stress response that puts them at risk of energy depletion and immunological depression, while placing undue strain on their developmentally immature respiratory, cardiac, and neurological systems.Here's more on the definitions:
Definitions are important here. The term cosleeping refers to any situation in which a committed adult caregiver, usually the mother, sleeps within close enough proximity to her infant so that each, the mother and infant, can respond to each other’s sensory signals and cues. Room sharing is a form of cosleeping, always considered safe and always considered protective. But it is not the room itself that it is protective. It is what goes on between the mother (or father) and the infant that is. Medical authorities seem to forget this fact. This form of cosleeping is not controversial and is recommended by all.
