I would like to know if the claim is literally true, that American (United States to be exact) babies cry significantly more then babies of all other cultures.  

If that is not true then is it true that babies from the United states cry more then children from any or all of culture/locations explicitly called out in the article, specifically Sioux, Kenya, Mexico, and South Korea?
