Give each child one colour of washable paint and a paintbrush. To make new colours, they must cooperate: 'You have yellow and your sister has blue. What happens if you mix them?' The activity creates genuine interdependence — neither child can make green, orange, or purple alone. This reframes the sibling dynamic from competition to necessity, providing a visceral experience of needing each other.

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

Parent tip

Set out construction paper and paintbrushes 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 creativity.

Why it helps

Genuine interdependence — where each person has something the other needs — creates the most effective context for developing cooperative behaviour. Colour mixing provides immediate, visible, magical proof that cooperation produces something neither child could achieve alone. This concrete experience of mutual benefit lays the cognitive foundation for understanding why sharing and cooperation matter — not because adults say so, but because the results are better.

Variations

  • Use playdough instead of paint — knead two colours together to see what happens.
  • Start with the three primary colours between three children for maximum mixing possibilities.
  • Add white paint as a shared resource that anyone can use to make pastel versions.

Safety tips

  • Use only non-toxic, washable paint designed for young children.
  • Cover the work surface and dress children in old clothes or aprons.
  • Supervise paint use to prevent it going near eyes or mouths.

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.
