Aboriginal Teachings

I was at a church meeting with Ashley's family last night, and there was a 3 month old there crying. I had learnt a technique from Prof. Gary Kerr at University of Montana that is used by aboriginal men in Australia. It's essentially whistling and humming simultaneously. It's also only done by men, and is very difficult for women to do. The idea is that the sound sooths children, and stops them from crying, and in some cases puts them to sleep. I tried it and was met with success. It seems to me that it works best when the cause of the crying is from general distress or discomfort, as opposed to crying for food.
