     "Most parents make well-meant efforts to set high goals to motivate and stimulate their children's learning and good behavior,"observes Sam Goldstein, a psychologist specializing in child development at the University of Utah. "But many don't understand their own child's limitations or strengths. 
     In fact, many potentialities and limitations—in intelligence, character and mental health- are laid down prior to birth. We may want our son or daughter to do better than we did at the same age, but if it's not in the cards, or genes, no amount of coaching or coaxing will move them much beyond their natural gifts. In fact, the pressure may have the opposite effect. In most cases, the parents' urge only adds to their children's anxiety.
     Trouble arises when we ignore the signs that a child isn't ready or able to live up to our expectations. If a child is not really good at what his parents are pushing him to do, he will be confronted with failures. And repeated failures may cause some children to set the bar too low for themselves, withdrawing from new experiences and missing out on opportunities to guarantee they won‘t fail again. When a child doesn't meet expectations, the parents may feel anger which shows up as annoyance or frustration. Children may see their parents' disappointment as rejection, and these feelings can lead to hostility, emotional withdrawal, lack of ability and conduct problems or immoral behaviors.
     The bottom line is that we must accept our children for who they are and allow them to become what they will be. But don't misinterpret acceptance as permissiveness. Let children do what they want when they want to; homework must be done, and family rules respected. It comes down to a delicate balance of control and acceptance.
     Often kids will give us the clue we need to help them set and achieve realistic goals. The benefits of taking a realistic view of your child may surprise you. When parents are accepting, loving and supportive, children are often motivated to exceed your expectations.
