A parent can easily say "no" 200-300 times a day to a young child. After a barrage of "no's," a child can become so inured to the pain that he stops listening. Obviously, a parent must set limits, but it is also essential to show empathy as you do so. Teaching children to face life's endless disappointments, losses and frustrations with determination and discipline is what helps them build ego-strengths! Even if they rant and rave and accuse you of being the meanest parent on earth, they will – one day - appreciate the fact that you cared enough to protect them.
