Weekend Reward

When children understand that rewards come with obedience, they work harder to attain the prize. Sit down with your children at the start of each week to decide the reward they earn at the week's end. Anything from ordering pizza, bowling, play dates or another favorite suffices as a strong motivator. Make it clear that your children are only rewarded if they get along with one another for the entire week. Setting a future goal for your children to earn with their good behavior makes it possible for them to spend time working as a team and less time as combating rivals.

In Their Shoes

Schedule a day for doing what one child loves to do, the alternate another day for what another child likes. This process develops an appreciation for each other. If one child loves going to the batting cage, for example, send the family out with shoes and helmets. If another child enjoys horseback riding, take another day to delve into this interest. Being in one another's shoes provides each sibling time to enjoy what their brother or sister loves to do. It also develops family time which further reduces sibling rivalry.

Date Night With Child

Every child wants to be the favorite of mommy or daddy. Though your children have to share you, they will appreciate the undivided attention that date night allows. Create a special time when your children do not need to vie for your love and can develop a relationship with you that is their own further minimizes sibling rivalry. If your schedule or budget doesn't permit a regular date night each week, then spend time exclusively -- 30 minutes or an hour -- with each child. If you’re married, alternate this child-specific time with your spouse.

Praise Game

A praise game with the siblings helps children see the good in each other. Gather your family regularly to say out loud the things they love about each other. The more children communicate the qualities they love in their siblings, the more they will believe them, and the less they will spend time fighting. Have children focus only on the positives. Model this behavior yourself with your partner so that your children know how the praise game works.
