Things to try now

What to do now

  • 11. Calmly intervene if biting occurs and separate the children to prevent harm.
  • 22. Encourage the biting child to use words like 'I’m upset' or 'I need help' instead of biting.
  • 33. Spend focused one-on-one time with each child to reduce rivalry.

What to say

  • “Biting hurts, and we use words to tell each other how we feel.”
  • “I see you’re upset. Can you tell me what’s wrong with your words?”
  • “Let’s find a way to share the toys so everyone can have fun.”

What to practice consistently

  • Regularly teach and reinforce phrases for expressing feelings and negotiating turns.
  • Set consistent family rules about physical behavior and consequences for biting.
  • Create daily or weekly one-on-one time with each child to strengthen individual bonds.

What to avoid

  • Taking sides or blaming one child over the other.
  • Ignoring physical aggression or allowing biting to go unaddressed.
  • Comparing siblings in ways that fuel competition or resentment.

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

What this usually involves

  • Sibling rivalry includes competition for parental attention and resources, often intensifying when children are close in age or a new sibling arrives.
  • Biting during sibling rivalry may occur as a nonverbal way to express anger, frustration, or to gain control.
  • Parents are advised to avoid taking sides and to help children use words to express feelings.
  • Teaching children conflict-resolution skills and praising positive communication helps reduce physical aggression.
  • Spending individual one-on-one time with each child can reduce competition and improve relationships.
  • Allowing children to resolve minor disputes on their own builds negotiation skills, with parental intervention reserved for physical or emotional harm.
