A child who is over-protected is never given a chance to learn from mistakes or to build confidence through handling problem-solving issues. An overly-controlling parent through her actions is telling a child that he is incapable of both making his own decisions and making it on his own. If a child does make an effort at a task, and the parent has to step in, this will only serve to make the child feel useless. After awhile, the child will stop trying. Lack of confidence and self-esteem often lead to alcohol and drug abuse which further a lack of motivation and poor success in career and relationships.
