Investigate the back of the head of most of your Asian co-workers eg. Chinese, Japanese. Our back of the head are usually flat as a board from sleeping on our backs; I don't recall any Asian cultures putting their child to sleep on their Stomach. For a while we slept on Tatami, the japanese straw floors, our little bassenette lies next to my wife so breast feeding was easy. Even without a bassenette one can put the baby a few feet away to the side of the room. Heck the whole floor was a bed anyways. It was good for our backs too. Scott Yang, MD Okinawa, JP
