Understanding Jealousy and Conflicts Between Children

Changing Needs

It is natural for children’s changing needs, anxieties, and identities to affect how they relate to one another. For example, toddlers are naturally protective of their toys and belongings, learning to assert their will at every opportunity. Therefore, if a younger sibling takes their toy, a toddler may react aggressively. School-aged children often have a strong sense of fairness and equality; thus, they might not understand why siblings of different ages are treated differently, or they may feel another child is receiving preferential attention. On the other hand, teenagers are developing a sense of individuality and independence, and they may resent having to help with household chores, watch over their siblings, or spend mandatory time together. All these differences can shape how children conflict with one another.

Individual Temperament

Your children’s individual temperaments—including their mood, disposition, and adaptability—as well as their unique personalities play a significant role in how well they get along. For instance, if one child is easily comforted while another is quickly upset, they may clash more frequently. Similarly, a child who craves attention and seeks comfort and affection from parents can trigger resentment in siblings who see this and desire the same level of attention.

Special Needs and Illness

Sometimes, a child’s special needs arising from illness or learning/emotional challenges may require parents to devote more time to them. Other children notice this imbalance quickly and may act out to get attention or out of fear regarding what is happening to their sibling.

Role Models

The way parents resolve problems and disagreements sets an example for their children. If you and your partner handle conflicts in a respectful, productive, and non-aggressive manner, your children are more likely to adopt these positive strategies when they have issues with one another. However, if children routinely see you shouting, slamming doors, and arguing loudly, they are very likely to pick up these negative habits.

What to Do When a Fight Starts

Separate the children until they calm down. Sometimes it is best to give them space and not try to resolve the conflict in the heat of the moment, which might only reignite the argument. If you want to turn this into a learning experience, wait until emotions have settled. Avoid focusing too much on who is to blame. Fighting takes two, and everyone involved carries some responsibility.

Next, try to find a "win-win" solution so both children gain something. If both want the same toy, perhaps there is a game they can play together. Remember, as children navigate conflicts, they also learn vital life skills—such as respecting another's perspective, compromising, negotiating, and controlling aggressive impulses.

Helping Children Get Along

Here are some simple everyday steps to help prevent conflicts: Set ground rules for acceptable behavior. Teach children to keep their hands to themselves, and avoid name-calling, yelling, or slamming doors. Encourage them to contribute to these rules—and the consequences of breaking them. This teaches children that they are responsible for their own actions, regardless of the situation or how provoked they feel, while discouraging negotiations over who was "right" or "wrong".

Do not let children convince you that everything must always be "fair" and "equal"—sometimes, one child simply needs more than the other at that moment. Be proactive in giving your children one-on-one attention tailored to their interests and needs. For example, if one child loves being outdoors, take a walk or go to the park. If another prefers reading a book, set aside quiet time for that. Ensure children have their own space and time to do what they want—playing with toys on their own, hosting friends without a younger sibling tagging along, or enjoying activities without the pressure of sharing.

Show and tell your children that your love has no limits. Let them know they are safe, valued, loved, and that their needs will always be met. Have fun together as a family. Whether watching a movie, playing ball, or enjoying a board game, you are establishing a peaceful way for your children to spend time and connect with one another. This reduces tension and brings you closer. Since parental attention is often what children are competing for, enjoyable family activities can significantly reduce conflict.

If your children frequently squabble over the same things (like video games or the TV remote), create a schedule showing who "owns" the item at what times of the week. (If they keep fighting, remove the privilege entirely). If conflict is frequent among school-aged children, hold weekly family meetings to review ground rules and highlight past successes in resolving disagreements. You can even set up a system where they earn points toward a fun family activity for cooperating and resolving conflicts peacefully.

Acknowledge that children need time apart from each other and from family dynamics. Whenever possible, arrange separate playdates or activities for each child. While one child is out, you can spend precious one-on-one time with the other. Keep in mind that children sometimes fight just to get their parents' attention. If you feel your patience wearing thin, take a step back or hand the reins over to your partner, who might have more patience in that moment.
