PARENTS should stop showing much love to a particular child. This act often makes the child feel superior thereby making them lack a sense of responsibility.
Sometimes those children grow up to bring shame to the family because they have been pampered into empty adults.
While most of the children you neglected, denied love maybe because of the experience associated with his/her birth suffers a great deal of inferiority complex which affects them emotionally, psychologically among their peers and they grow up with it until they can find solutions to it.
No one knows tomorrow, you never can tell who will make you proud tomorrow.
Even though the child who feels inferior will hold no grudge against you, but I know definitely your conscience will judge you forever by the time he/she makes it in Life.
PLEASE help our children have self worth.
