To those who were interested, I finally found the original article on stress
and cortisol levels in infants and relationship to crying.  I originally, a
couple of weeks ago responded to posting re Ezzo and included an abstract of
this article below that I use from Brown U Child and Adolescent Behavior
Newsletter.  This more complete version is even more compelling than
abstract.  so, as promised for those who wanted it:

<< 17/02/98 USA: STRESSED BABIES MAY BE PRONE TO TROUBLE LATER-EXPERTS.


 By Maggie Fox, Health and Science Correspondent
 PHILADELPHIA, Feb 17 (Reuters) - Psychiatrists said on Tuesday there may be a
 physical basis linking stressed-out babies to personality disorders in
 adulthood.
 Babies who are made to sleep alone or are not picked up and comforted enough
 may
 grow up susceptible to post-traumatic stress disorder (PTSD) and personality
 problems, said Dr. Michael Commons of the Harvard Medical School, and
 colleagues.
 The idea that babies need physical contact is not new -- that is why they are
 no
 longer swaddled in tight blankets and left to cry for hours. But researchers
 speaking at the annual meeting of the American Association for the
Advancement
 of Science said they were starting to find evidence of physical changes in
the
 brain caused by stress in infancy.
 "Parents in most cultures have infants sleep with them," Commons told a news
 conference. "As an infant, sleeping by yourself is very stressful. We can see
 this because infants cry."
 Scientists have also found levels of the stress hormone cortisol to be much
 higher in crying babies. Commons suggested that constant stimulation by
 cortisol
 in infancy caused physical changes in the brain.
 "It makes you more prone to the effects of stress, more prone to illness
 including mental illness and makes it harder to recover from illness,"
Commons
 said. "These are real changes and they don't go away."
 He said his team was doing studies with Kenyans, people of Mayan descent and
 residents of Boston.
 In the West, children are encouraged to be self-sufficient and face danger
 alone. "They don't have the emotional resources to seek comfort and consoling
 and the experience becomes unspeakable," Commons said.
 Other cultures teach infants to stay close and look to others for emotional
and
 physical support, he said.
 "The infants sleep touching the parents," he said. "They are carried around
 touching the parent or some family member."
 Commons cited theories that such constant support kept down levels of
cortisol,
 and helped the cortical structures in the brain develop better.
 He said illnesses such as PTSD and phobias, on the rise in industrialized
 countries such as the United States, barely existed in more primitive
 societies.
 But Commons conceded he had no proof of his theory, although he planned more
 tests such as PET scans, which can show blood flow in the brain and indicate
 what structures in the brain are working.
 But he said parents should think carefully about how they treat infants. "I
 think infants should be rubbed and hugged and kissed," he said. Children in
day
 care should not be put to sleep in separate cribs, he said. "They should
sleep
 touching each other."
 Commons conceded the growing prevalence of post-traumatic stress disorder
could
 be because it had become fashionable to talk about.
 "I think the cultural fad of PTSD is probably a slight, slight overreaction,"
 he
 said. "But I work in a mental hospital and clinical instances of PTSD and
 phobia
 are just way, way up. I think there's a strong organic basis."
