Sibling rivalry describes the competitive relationship between siblings. Often competition is the result of a desire for greater attention from parents. However, even the most conscientious parents can expect to see sibling rivalry in play to a degree. Children tend to naturally compete with each other for not only attention from parents but for recognition in the world.
There are many things that can influence and shape sibling rivalry. A grandparent who favors one grandchild over another is as likely to influence how siblings behave to each other, as is parental treatment. Birth order is also a factor. No child can quite understand the introduction of a new baby into the house, and even older children may be troubled by this. The feeling of being replaced or supplanted is often the cause of jealousy on the part of the older sibling.
A child’s personality can also have an effect on how much sibling rivalry will occur in a home. Some kids seem to naturally accept changes, while others may be naturally competitive, and exhibit this nature long before a sibling enters the home.
