These differences, the close quarters in which many siblings live, competition for parents' attention and jealousy contribute to sibling rivalry. Arguments between siblings can be very frustrating for parents, but a certain amount of rivalry is normal and it can be beneficial to children. By arguing with brothers and sisters, children learn how to resolve conflicts, cope with competition and practice negotiation skills. Even though some conflict can be positive, parents should set limits. Always step in when arguments shift from yelling to hitting, and explain that physical violence will not be tolerated.
Many children argue because they are jealous.
Older children might think their younger siblings receive too much attention, while younger children might think older siblings have too much freedom. To reduce feelings of jealousy, set aside some time to spend alone with each child. This will give the children some needed time away from one another, and it will also give you an opportunity to learn more about each child. Resist the temptation to compare children's abilities. One child may do better academically while others have more musical or athletic talents.
