   Babies born and not nurtured, die. You must remember hearing
   about that nursury in the 1930s where 1/2 the babies were
   cuddled and talked to and the other half were just fed, never
   looked at, never hugged.

   The non-hugged babies died. They had nothing to form their sense
   of self "against".
