But there are some childhood battles still hard to forget for some people. There are many reasons a child may feel jealousy toward a sibling. One reason, maybe one child is more talented than the other, or maybe one child feels they receive less attention than a the other. This is related to another common cause of sibling rivalry – competition. These negative feelings can cause a person to demonstrate negative actions toward a brother or sister, usually causing major problems within the entire family and often leading one sibling to sever all communication with the other. There are some steps that you can do to fix the sibling relationship, such as: identify the conflicts that sparked feelings of jealousy and rivalry. Then, acknowledge the major events in life that may have heightened these negative feelings, such as career success, marriage, and having children.
