Give the siblings a pile of building blocks and one simple rule: take turns adding one block at a time. They build something together — a tower, a road, a house, whatever emerges. The key rule is that nobody knocks it down until both agree it's time. This single constraint teaches negotiation, patience, and collaborative play. The shared creation gives them something to be proud of together rather than competing over.

From our family

The ‘no knocking down until both agree’ rule was a game-changer for my two. It taught negotiation without us having to lecture about sharing — they just figured it out because the game needed it.

for calmer, lower-pressure moments, especially when you need an indoor option.

Parent tip

Set out building blocks before inviting your toddler in so the first minute feels smooth.

What success looks like

A good outcome is a few minutes of engaged play, some back-and-forth with you, and a small sign of progress in cognitive skills.

Instructions

Get ready
  • Set out a pile of building blocks between both children
  • Explain the rule: 'Take turns — one block each, and we only knock it down when everyone says yes'
  1. Set out a pile of building blocks between both children
  2. Explain the rule: 'Take turns — one block each, and we only knock it down when everyone says yes'
  3. Let the younger child go first
  4. After each block, say: 'Great! Now it's [sibling]'s turn'
  5. Narrate what's happening: 'Wow, you're building a tall tower together!'
  6. If someone wants to knock it down, ask: 'Does everyone agree? Let's count down together!'
  7. Celebrate the crash as a team: 'You built that together — brilliant!'

Why it helps

Shared construction tasks require turn-taking, spatial negotiation, and impulse control — three skills that underpin cooperative play. The 'no knocking down' rule specifically targets the impulsivity that causes sibling friction, while the agreed demolition at the end provides a satisfying, sanctioned release. Building something together also creates a shared identity: 'We made that.'

Variations

  • Challenge them to build as tall as one of them — 'Can you make it taller than you?'
  • Use different materials: cardboard boxes, cushions, or empty containers.
  • Take a photo of their creation before the big crash — start a gallery of their builds.

Safety tips

  • Use lightweight blocks that won't hurt if the tower falls unexpectedly.
  • Sit nearby to mediate turn-taking disputes gently.
  • If one child is much younger, let them hand blocks to the older child to place — they're still participating.

When to pause and seek extra support

Stop if your child becomes distressed, unsafe, or consistently frustrated by the activity. If play, behaviour, or development worries keep showing up across settings, check in with a qualified professional.
