there is a lot of culture behind this. friends i visited left their baby in a room crying while they were entertaining guests as if it was the most normal thing in the world. they were otherwise very loving and caring towards their children, so to me this seemed rather out of place. but it looked like that was just how they did it and i guess everyone else from their culture too.

i also think that many parents are being led to believe that letting the kid cry it out is for the well-being of the child. so some will do it even if it goes against their own feelings.
