Sibling Rivalry: Adult Siblings
As siblings grow into mature adults, they hope and expect rivalries will recede into the past. For most siblings this is the case, but for some rivalry continues to burn deep. In some cases, new rivalries pop up. When sibling rivalry persists into adulthood, the conflict and self-doubts can be devastating. For those suffering these negative consequences, it's important to learn about sibling rivalry and how to minimize it.
