How Long Does a Typical Sibling Rivalry Last?

A month? Five years? All of eternity?

According to a poll of adults with at least one sibling, just over 50 percent say they still have a competitive relationship. Even more than that admit that they still argue over who’s the “favorite child.” Things people most competitive with their brothers and sisters over are career success. but Housing success was a close second….like who bought their home first or who’s is the biggest. Other battles include Sport skills, parenting, and who gives the best gifts.
