Room sharing: what are the options?

Parents usually land on one of these 4 approaches.

  1. 1. Own rooms

    Each child has a bedroom.

  2. 2. Share when young, separate later

    Children share while small and get their own rooms later.

  3. 3. Share by choice

    Children share only if they want to.

  4. 4. Rule by age or gender

    You separate children at a set age, or when a brother and sister reach a certain age.

Room sharing: what does the evidence say?

Your call. No outcome evidence picks a winner. Preference, culture, money and logistics decide.

No outcome research gathered on this yet — treat it as a preference.

What else is worth knowing?

Whether children share a bedroom depends on space as much as preference. Sharing is common around the world and many siblings enjoy it. Some families separate children at a certain age.

Questions to ask each other

  • Did we share rooms and what do we remember?
  • What would make sharing work or not?
  • When would we want them to have their own space?
