Parent tip
Set out construction paper and crayons before inviting your toddler in so the first minute feels smooth.
Sibling Treasure Team
Hide items around the house that siblings must find together — each child gets half the clues, so they need each other to succeed.
Activity details
Instructions
- While the children are in another room, hide three or four small treasures around the house — a toy car, a sticker sheet, some raisins.
- Draw two simple picture clues for each treasure: one clue shows the room, the other shows the specific spot. Give each child one clue per treasure.
- Bring the children together and say: 'There are treasures hidden, but you each only have HALF the map. You have to work together!'
- Let the older child show their clue: 'My picture shows the kitchen!' Then the younger child shows theirs: 'Mine shows something under something!'
- Guide them to share information: 'So the treasure is in the kitchen, under something. Let's look together!'
- When they find the treasure, celebrate the teamwork: 'You found it BECAUSE you worked together! Neither of you could have done it alone.'
- Continue through all the treasures. If squabbling starts, pause and say: 'Remember — you need each other for this!'
- End with a shared reward that must be split equally — a plate of fruit they divide together, or a sticker each from the same sheet.
What success looks like
Intense focus, even briefly. Watch for the small ‘aha’ moment when they figure out how something works.
Sibling conflict often erupts because children feel they are competing for the same prize — a parent's attention, a favourite toy, the bigger biscuit. This activity flips that dynamic by making cooperation essential. Items are hidden around the house, and each child receives only half of the clues needed to find them. Neither can succeed alone, transforming the sibling relationship from rivalry into partnership. The shared victory releases dopamine for both children simultaneously, building a positive association between working together and feeling good.
Why it helps
The EYFS framework identifies sharing and cooperative play as key social development milestones that children build through guided play experiences. Cooperative goal structures — where success depends on mutual effort — are one of the most well-evidenced strategies in social psychology for reducing conflict between groups, and the same principle applies to siblings. When children physically experience that they cannot succeed without each other, the relational dynamic shifts from competitor to ally. Shared positive emotions during the discovery moments further strengthen the sibling bond through simultaneous dopamine release, creating emotional memories of teamwork.
Variations
- For younger pairs, skip drawn clues and instead whisper one clue to each child: one knows the room, the other knows 'high or low.'
- Add a timer to create gentle urgency — 'Can you find all the treasures before the egg timer runs out?'
- Let the children hide treasures and create clues for you, practising cooperation in the planning phase too.
Safety tips
- Hide treasures in accessible, safe locations — nothing up high, near heavy objects, or in spaces where a child could get stuck.
- Ensure the shared reward is genuinely equal to prevent post-game conflict — prepare two identical portions.
- If one sibling is significantly older, give them the harder clue so neither child feels they are doing all the work.
