Sibling rivalry.

Rivalry occurs between most, if not all, siblings to a varying degree. Rivalry may be manifested as a verbal or physical attack, frustration, persistent demands for attention, or as regressive phenomena. When handled properly, healthy competition among siblings will lead to the acquisition of social, interpersonal and cognitive skills that are important to the development of the child. Mismanagement of the competition may lead to psychological problems later in life. The appropriate spacing of children and the preparation of existing children for a new sibling help to reduce sibling rivalry. Family situations that will potentially lead to jealousy should be avoided. Parents should not make comparisons between siblings and favoritism should be avoided. When episodes of sibling rivalry develop, the cause rather than the manifestation of the rivalry should be treated. Patience, love, understanding, common sense, and humor are important parental skills necessary to minimize sibling rivalry.
