What is Sibling Rivalry?

Anyone with a sibling can tell you a story about sibling rivalry. Whether it is a debate over “the favorite,” a time where they felt inferior or superior to their sibling(s), or a story about a conflict over anything they shared, sibling rivalry finds a way to show up in every family. Between viral videos and headlines, television, and movies, sibling rivalry is viewed culturally as a normal part of life. While this may be true, it is important to understand its impact and when it goes too far.
