Don't let past mistakes interfere with plans for today or the future. Do learn from your past experiences. Do set realistic goals. Do look for new challenges and opportunities. Do accept yourself.
Parents can do a lot to build their child's sense of self-esteem.
It's important to understand normal childhood development, accept shortcomings, and provide realistic expectations. When your child fails to meet these expectations, make it known that you still love her or him. Give your child responsibility that is consistent with his or her age, and help provide opportunities for success. When negative behaviors call for punishment or restrictive action, make it clear that while you do not like the behavior, you do like the child. Really listening to what your child has to say will tell the child that you think he or she is a worthwhile person.
