Your job is easier when you tailor your parenting skills to your child's temperament. Any parent can tell you that his or her child arrived with certain temperament traits and that those traits endure to this day.
Some babies are sensitive to stimulation and cry easily.
Other babies enjoy people and seek out interaction. Others shrink from new people and situations. All of these are temperament-based traits and stay with a person as they grow. Temperament traits affect family life profoundly. If the child's temperament is difficult all by itself, if the child's temperament doesn't mesh well with his environment, or if the child's temperament doesn't match his parents', then there will be conflict.
