In early years settings, children naturally spend most of their time with their own peer group. This is valuable: they build friendships with children at a similar stage of development, practise turn-taking, learn how to negotiate, and find common interests. But there is also a quiet strength in allowing children to play, explore and collaborate with those who are older or younger than themselves.
Siblings at home
Mixed-age play happens at home all the time. Older siblings show younger ones how to stack blocks or zip up a coat; younger children bring curiosity, imagination and energy; families learn to adapt to each other’s needs. Later, at school, the playground becomes a natural mix of ages again. As adults, the pattern continues – we work alongside colleagues of all ages, learn from those with more experience, and support those who are newer to a task. Helping children understand how to connect with people who are not exactly like themselves is a valuable life skill.
Benefits of mixed-age play in Early Years
For young children, mixed-age play offers a range of small but meaningful benefits. Younger children often gain confidence when they are invited into play by older peers. They copy language, movements and ideas, and learn how to join in with more complex activities. Older children develop kindness and responsibility – not in a pressured way, but simply through the experience of helping, waiting, showing, and adjusting their play for someone else’s needs. Staff can gently encourage these moments by noticing when a child offers help, by naming kindness explicitly, and by creating opportunities for children to work together.
There is also a wellbeing aspect. Children who spend time with a slightly wider age range tend to show resilience in social situations. They learn to adapt, to read social cues, to tolerate frustration and to seek help when needed. When staff model phrases such as “Can you show me?” or “Would you like some help?”, children learn that asking for support is a strength rather than a weakness. Mixed-age play provides many opportunities for these interactions to happen naturally.
Nursery staff involvement
From a practitioner’s point of view, there are advantages too. Staff who see their key children playing with other age groups often notice new aspects of a child’s development – a skill that may not appear within their usual peer group, or a moment of confidence that emerges in a different social setting. Mixed-age play allows educators to observe how a child adapts, leads, follows, problem-solves or nurtures others, all of which deepens their understanding of that child’s learning journey.
These moments also help staff understand how children with additional needs respond in real-life social situations — whether that’s a child with anxiety feeling confident with a familiar older peer, or a child with a physical disability finding a new role within a group. Mixed-age play reveals strengths that aren’t always visible in age-grouped rooms.
Building childhood friendships
At Blue Windmill Day Nursery, our approach to mixed-age opportunities is thoughtful, purposeful and rooted in kindness. While children spend most of their day in age-appropriate rooms, there is real value in coming together at certain times – in the garden, during creative projects, or through shared activities. These moments help children build friendships across the nursery, strengthen their sense of community and discover that learning from older and younger friends can be one of the most natural things in the world.
