Sibling Rivalry in a Blended Family

Why Sibling Rivalry Happens in a Blended Family

 

1. Competition for a Parent’s Attention

When a parent remarries, children may feel like they have to compete for love and time—especially if they were used to having their biological parent all to themselves.

💡 Tip: Set aside one-on-one time with each child so they feel special and secure in their relationship with you.

 

2. Different Upbringings & Household Rules

Each child comes from a different background, and what was "normal" in one home may not be the same in the new family.

💡 Example: One child might be used to eating dinner in front of the TV, while the other is used to family meals at the table.

✔ Tip: Create new house rules together so all children feel included in setting expectations.

 

3. Jealousy & Favoritism (Real or Perceived)

Children are highly sensitive to fairness. If they feel that their step-siblings are getting more attention, privileges, or affection, resentment can grow.

💡 Tip: Ensure that rules, rewards, and discipline are applied fairly across all children. Avoid phrases like "You're older, so you should know better," which can make an older child feel unfairly treated.

 

4. Loyalty Conflicts

Some children feel guilty for bonding with a step-sibling, as if they’re betraying their biological sibling or parent.

💡 Tip: Reassure them that it’s okay to love both families. Encourage openness and respect for each child's emotions.

​

5. Sharing Space & Personal Belongings

If children move into a shared home or start sharing a bedroom, territory battles can arise.

💡 Tip: Give each child some personal space—even if it’s just their own corner of a shared room. Let them have some control over their belongings.

How to Help Step-Siblings Bond & Reduce Rivalry

While sibling rivalry is natural, parents can take steps to help children build trust and respect each other.

​

✅ 1. Let Relationships Develop Naturally

You can’t force siblings to like each other—but you can create opportunities for bonding.

💡 Tip: Instead of pushing closeness, start with small, positive interactions, like:
✔ Playing a board game together
✔ Working on a fun family project (puzzles, cooking, crafts)
✔ Watching a movie or show that everyone enjoys

​

✅ 2. Treat All Children Fairly (But Not Identically)

Fairness doesn’t mean treating everyone exactly the same—it means recognizing that each child has different needs.

💡 Tip: If one child gets extra attention (e.g., help with school or emotional struggles), explain why to the others so they don’t feel overlooked.

​

✅ 3. Create New Family Traditions Together

Blended families need new traditions to help everyone feel like part of one family.

💡 Ideas for new traditions:
✔ A special weekly family night
✔ A holiday tradition that blends elements from both families
✔ A yearly trip or outing that everyone looks forward to

​

✅ 4. Establish Clear Family Rules

Having consistent house rules helps prevent conflict.

💡 Tip: Sit down as a family and decide together on:
✔ Household chores & responsibilities
✔ Screen time & bedtime rules
✔ How conflicts between siblings should be handled

When kids feel involved in setting rules, they’re more likely to respect them.

​

✅ 5. Encourage Teamwork & Cooperation

Instead of making everything a competition, find ways for siblings to work together.

💡 Tip: Give them a common goal, like:
✔ A baking challenge where they have to work as a team
✔ Cleaning up together to earn a shared reward
✔ Playing a cooperative video game instead of a competitive one

​

✅ 6. Teach Healthy Conflict Resolution

Disagreements will happen—but how siblings handle them makes all the difference.

💡 Tip: Teach children to use “I” statements when expressing feelings:
❌ "You always take my stuff!"
✔ "I feel upset when my things are used without asking."

Encourage problem-solving instead of yelling or physical fights.

​

✅ 7. Respect Each Child’s Individuality

Some children won’t bond quickly—and that’s okay. Every child is unique, and some may be more independent.

💡 Tip: Avoid comparing siblings—even in a positive way. Instead of saying:
❌ "Why can’t you be more like your stepbrother?"
✔ Say: "I appreciate how each of you brings something special to our family."

​

✅ 8. Allow One-on-One Sibling Time

Sometimes, step-siblings get along better without parents hovering.

💡 Tip: If siblings have a shared interest (e.g., sports, music, gaming), encourage them to spend time together naturally, without pressure.

​

✅ 9. Be Patient—Bonding Takes Time

Blended sibling relationships don’t form overnight. Some siblings may click instantly, while others may need months or years to develop a bond.

💡 Tip: Celebrate small wins—even if it’s just one positive interaction at a time.

​

It’s normal for siblings—especially step-siblings—to struggle at first. But with patience, consistency, and intentional effort, blended families can become close and supportive over time.
