>>I presume that the cosleeping that has happened for years around the world have included both parents. Not necessarily. Often the mother sleeps with the youngest, and the father with the older children. Also in polygynous societies the husband takes turns sleeping with alternate wives and their children on different nights, so dad would only be in the room every second or third night. Other children would be sleeping with the mom, too though, so you might have a baby, a 4 year old, an 8 year old, a 12 year old, etc. ---------------------------------------------------------------------------- ------- Katherine A.
