When parents are emotionally unavailable, a child tends to pull away from needing them. According to Daniel J. Siegel, the author of, "The Mindful Brain" this is called an avoidant childhood attachment. If parents are inconsistently attuned to a child, with frequent intrusions of their own state into their child, then the child develops an ambivalent/anxious relationship with his parents. In the event the parent is the source of terrified behaviors that induces in the child a state of fear without resolution, such an attachment is termed by Siegel as disorganized attachment. And of course, there might be several cases where upbringing of a child is clearly reflected in the parent's influence on the child.  Since each child goes through different life experiences during his childhood, these experiences may manifest later in adulthood with emotional or psychological challenges.  

Interestingly, a natal chart clearly reflects the challenges that a child is likely to face.  How those challenges are going to be met, in large parts, depends on the parenting the child is going to get.  From that standpoint, a thorough analysis of child's natal chart will certainly help parents to create and
provide a healthy environment in which child is emotionally and psychologically nourished with healthy attachment to his parents.

A proper guidance, based on a natal chart interpretation will certainly minimize, if not completely eliminate, the issues a child might face in his adulthood.
