## TLDR

- Sibling fights are normal and are practice for negotiating and repairing.
- Stay out of small bickering, coach when they're stuck, and step in right away for hitting or when one child keeps losing.
- Don't compare, remember fair isn't always equal, and give each child one-on-one time.

## Why siblings fight

- Conflict between siblings is normal and very common, especially when children are close in age
  or one is a toddler. It peaks for many families when the younger child starts grabbing and the
  older one has things to protect.
- Underneath most fights: competing for a parent's attention, different temperaments, being tired
  or hungry, boredom, or a stage where one child is going through something big.
- Handled well, sibling squabbles are practice for negotiating, sharing and repairing, skills
  children use for life.

## Stay out, coach, or step in

- **Stay out** of small bickering when no one is getting hurt. Give them a chance to solve it.
- **Coach** when they're stuck: describe the problem, then hand it back. "Two kids, one scooter.
  What could you do?"
- **Step in right away** for hitting, biting, pushing, or when one child is much younger or keeps
  losing. Separate first, talk later: "I won't let you hit. Let's take a break."

## How to coach a fight

1. Calm things down: separate if needed and name feelings on both sides.
2. Listen to each child without deciding who's right.
3. State the problem simply.
4. Ask for ideas, and add your own if needed (take turns with a timer, find another toy, play
   together).
5. Let them pick, and check back later.

## Habits that lower rivalry

- **Don't compare.** "Why can't you be like your brother?" breeds resentment. See the sibling
  comparison guide.
- **Fair isn't always equal.** Give each child what they need, not the exact same thing. "You'll get
  new shoes when yours are too small."
- **One-on-one time.** Even 10 minutes a day alone with each child reduces jealousy. See the
  everyday connection guide.
- **Protect each child's special things.** Let the older child keep certain toys out of a toddler's
  reach.
- **Avoid fixed roles** like "the wild one" or "the helper." Children live up to labels.
- **Notice the good moments:** "You two figured that out together."

## Common mistakes

- Always making the older child give in because they "should know better."
- Forcing instant apologies. A sincere repair later, like helping rebuild a tower, means more.
- Getting pulled in as the judge for every tattle. Ask, "Is someone hurt or in danger? If not, can
  you work it out?"

## Many kinds of siblings

- Step-siblings, half-siblings, foster siblings and cousins being raised together often have extra
  feelings about belonging and fairness. Give these relationships time, and give each child private
  time with their own parent.
- Twins and multiples may need extra help being seen as individuals. See the twins guide.
- Siblings with a disability or chronic illness can stir feelings of jealousy or worry in the other
  children. Name it, and make space for both.

## When to check in

- Mention it to your pediatrician if fighting is constant and intense, one child is often hurt or
  frightened, or a child seems sad, anxious or withdrawn because of a sibling.
- A family therapist can help when the conflict is shaping daily life at home.
