KEY TAKEAWAYS
- Mixed age grouping — or “family grouping” — is deliberate, research-backed practice, not a logistical necessity.
- Younger children develop faster by observing older peers; older children strengthen their own brain development by teaching and leading.
- 360 maintains required educator-to-child ratios at all times — safety and supervision are never reduced when groups come together.

Over the course of the day, you may notice that your child has spent time with peers from different rooms; most commonly in the early morning, late afternoon, or when groups are outdoors together. It’s a question we’re asked from time to time, and it’s a good one. Like everything we do, the decision to ‘family group’ is deliberate and grounded in both research and regulation.
Why Young Children Learn So Much From Each Other
First, it’s worth understanding that young children learn incredibly quickly through social interaction. In the early years, the brain is forming connections at a remarkable rate, and much of that development happens through watching, imitating, negotiating, and collaborating with others.
One of the most powerful learning environments for young children is a mixed-age setting.
Developmental psychologist Lev Vygotsky described how children learn best when they interact with someone just slightly more capable than themselves. He called this the “zone of proximal development.” In practical terms, this means younger children often progress faster when they can observe older children demonstrating new skills; whether that’s climbing a structure, negotiating turns in a game, or experimenting with language.
The Benefits for Older Children Too
Older children benefit just as much. When a four-year-old shows a younger child how to use a trike safely or explains the rules of a game, they are doing something incredibly powerful for their own brain development: they are teaching! Explaining ideas strengthens neural pathways related to memory, language, and executive functioning – the brain systems responsible for planning, flexible thinking, and self-regulation.
Research from the Harvard Center on the Developing Child consistently shows that these executive functioning skills are among the strongest predictors of later academic success.
For this reason, high-quality early childhood programs often create intentional opportunities for children of different ages to interact, particularly in environments that support collaborative play. Outdoor spaces are especially valuable for this, as they provide larger areas for physical challenge, cooperative games, and imaginative play across age groups.
What About Arrival, Departure and Outdoor Time?
You may also see groups coming together during arrival and departure times. This reflects the natural rhythm of the day. Families arrive at different times, siblings often want to see each other, and children seek out friendships that extend beyond the walls of one classroom. Allowing these interactions supports children’s sense of belonging and community.
Safety, Supervision and Ratios
Importantly, when groups come together this does not mean supervision or structure is reduced.
We continue to maintain or exceed the educator-to-child ratios required under the Education and Care Services National Regulations. Safety and supervision remain the highest priority at all times.
Our younger children also have a primary educator who maintains close oversight of their wellbeing, routines, and learning. Even when children are interacting with a wider group of peers, their primary caregiver remains responsible for ensuring their needs are met and that they feel secure and supported throughout the day.
What the Regulations Say
Families sometimes ask whether the regulations say anything specific about mixing age groups. The answer is that the regulations do not require children to remain in a single room or age group throughout the day. Instead, the law focuses on ensuring that children are adequately supervised and that appropriate educator-to-child ratios are maintained.
The key requirements sit within the Education and Care Services National Regulations, particularly those relating to educator-to-child ratios and supervision (including Regulations 115, 122, 123 and 165). These regulations require services to maintain appropriate ratios based on the ages of children present and to ensure educators can effectively supervise all children in their care.
In other words, the regulations recognise that early learning is social and relational. They allow services flexibility to create learning environments that reflect how children naturally learn; through interaction, observation, and collaboration, while maintaining strong supervision and safety practices.
Our Approach at 360
At 360 Early Education, decisions about groupings are guided by research, professional knowledge, and the principles of the Early Years Learning Framework, which emphasises learning through relationships, belonging, and shared experiences.
When children learn alongside peers of different ages, whether building together in the sandpit, negotiating the rules of a game, or helping a younger friend climb the ladder, they are developing far more than a single skill. They are learning how to cooperate, lead, empathise, solve problems, and support one another.

FAQs
Why is my child sometimes in a mixed age group at childcare — is this normal?
Yes, and it’s entirely intentional. At 360, the decision to ‘family group’ is deliberate and grounded in both research and regulation. Children learn through watching, imitating, negotiating and collaborating — and mixed age settings create powerful natural opportunities for all of this, particularly during arrival, departure and outdoor play.
Is it safe for my younger child to be grouped with older children?
Absolutely. When groups come together at 360, educator-to-child ratios are maintained or exceeded under the Education and Care Services National Regulations. Younger children retain their primary educator, who maintains close oversight of their wellbeing and routines at all times.
What are the developmental benefits of mixed age grouping for my child?
Both younger and older children gain from mixed age grouping. Younger children progress faster by observing older peers demonstrating new skills. Older children strengthen their memory, language and executive functioning — the same skills that research from the Harvard Center on the Developing Child identifies as among the strongest predictors of later academic success — by explaining ideas and taking on leadership roles.
