Things to try now

What to do now

  • 11. Establish and clearly communicate family rules that physical aggression is unacceptable.
  • 22. Teach children simple phrases to express their feelings, such as 'I don’t like it when you take my toys. Can I have a turn next?'
  • 33. Schedule 10-15 minutes of focused one-on-one time with each child today to strengthen your individual connection.

What to say

  • “I see you're upset. Can you tell me what you’re feeling with words?”
  • “Remember, we don’t hit in our family. Let’s use our words to solve this problem.”
  • “I’m here with you, but I won’t let anyone get hurt. Let’s find a better way to play together.”

What to practice consistently

  • Regularly narrate and label emotions during calm moments to build emotional literacy.
  • Encourage siblings to negotiate and solve minor conflicts independently before stepping in.
  • Create structured family activities that require cooperation rather than competition.

What to avoid

  • Taking sides or showing favoritism between siblings.
  • Comparing siblings’ behaviors or achievements.
  • Intervening immediately in every minor dispute, which can hinder conflict-resolution skill development.

These are common approaches mentioned in sources and by parents. They are informational, not prescriptive.

What this usually involves

  • Recognizing sibling rivalry as a normal part of development that can intensify with age proximity or family changes
  • Setting clear family rules that physical aggression is unacceptable
  • Helping children express feelings verbally rather than physically
  • Spending regular one-on-one time with each child to reduce competition for parental attention
  • Allowing children to resolve minor disputes independently to build conflict-resolution skills
  • Intervening calmly and firmly when conflicts become physical or emotionally harmful
