Parallel play is when young children play right next to each other but don’t actually interact. Two toddlers might sit side by side building with blocks, each constructing their own tower without sharing pieces or coordinating their designs. It looks like they’re ignoring each other, but something important is happening beneath the surface: they’re learning how to be comfortable around peers, observing new ways to play, and building the social foundation they’ll need for true cooperation later on.
Where Parallel Play Fits in Development
In the 1930s, sociologist Mildred Parten mapped out six stages of play that children move through as their social skills mature. The progression starts with unoccupied play (random movements with no clear purpose), then solitary play (playing alone), onlooker play (watching other kids without joining), parallel play, associative play (playing alongside others with some interaction but different goals), and finally cooperative play (working together toward a shared goal).
Parallel play typically shows up between ages 1 and 3, though it can start earlier and often continues well past the toddler years. It sits at a pivotal point in the sequence. Before parallel play, children either play alone or simply watch. After it, they begin talking to each other and loosely sharing toys during associative play. Think of parallel play as a warm-up exercise. Children practice skills and absorb new ideas by working side by side on similar activities before they’re ready to coordinate with someone else.
What It Looks Like in Real Life
Parallel play can be easy to miss or misread. A parent at a playgroup might worry that their two-year-old is “not playing with the other kids” when the child is actually in a perfectly normal and productive stage. Here are some common examples:
- Art table: Two children sit next to each other coloring, each working on their own picture without swapping crayons or commenting on each other’s drawings.
- Sandbox: One child digs a hole while another fills a bucket three feet away. They’re aware of each other but don’t combine efforts.
- Toy cars: Two toddlers drive cars on the same stretch of carpet, but their routes and storylines never overlap.
The key feature is proximity without direct engagement. The children choose to be near each other, and they often gravitate toward the same type of activity, but each one is running their own show.
Why Parallel Play Matters
It’s tempting to view parallel play as a lesser version of “real” playing together, but it serves several critical developmental purposes.
First, it builds social comfort. Toddlers are still figuring out that other children have their own thoughts, feelings, and intentions. Sitting near a peer without the pressure of negotiation or turn-taking lets them get used to another person’s presence at their own pace. These early peer interactions form the foundation of prosocial skills. When a child notices that another kid is upset after falling, for instance, they’re developing awareness that other people have emotional experiences too.
Second, parallel play is a powerful learning channel. Children are natural imitators. A toddler stacking blocks in a simple tower might glance over and see a peer placing blocks in a different pattern, then try it themselves. This kind of observational learning happens constantly during parallel play, even though the children never speak to each other.
Third, it helps with language development in a low-pressure way. At this age, language lags far behind what children actually understand. Toddlers often have rich cognitive lives but limited ability to express frustration, excitement, or ideas in words. Parallel play lets them engage socially without relying on verbal skills they haven’t mastered yet, reducing stress while they continue building vocabulary by hearing the sounds and words around them.
Parallel Play in Neurodivergent Children
While neurotypical children generally move through parallel play between ages 1 and 5, neurodivergent children often stay in this stage longer, sometimes into their early teen years. This isn’t a problem to fix. For many neurodivergent kids, parallel play is a genuinely comfortable and productive way to socialize. It offers connection without the overwhelming demands of direct interaction, eye contact, or rapid conversational turn-taking.
Over time, parallel play can serve as a bridge to more cooperative play and relationship building for neurodivergent children, just as it does for younger neurotypical kids. The timeline is simply different. Recognizing parallel play as a valid social strategy, rather than a deficit, helps caregivers support neurodivergent children where they are instead of pushing them into interactions they’re not ready for.
How to Support Parallel Play at Home or in Groups
The most effective thing adults can do is set up the right environment and then step back. Children need enough physical space to play side by side without bumping into each other or competing over a single toy. A dedicated play area where two or three kids can spread out comfortably makes a big difference.
Providing duplicates of popular toys is one of the simplest and most effective strategies. If there’s only one set of building blocks, conflict is almost guaranteed. Two identical sets let children play with the same materials at the same time without needing to negotiate sharing, which is a skill that comes later. Open-ended materials work especially well: playdough, crayons, sand toys, water play supplies, and simple board games designed around simultaneous action rather than strict turn-taking.
The question of how much adults should get involved is more nuanced than it might seem. Research perspectives range from viewing adult involvement in children’s play as disruptive interference to seeing it as a way to enhance learning. The middle ground that most child development experts recommend is being responsive and sensitive to children’s cues while fostering their autonomy. That means staying nearby, showing interest if a child seeks your attention, and resisting the urge to direct the play or force interaction between children. If two toddlers are happily building separate towers next to each other, there’s no need to say “Why don’t you build one together?” They’re doing exactly what their development calls for.
When Parallel Play Shifts to Social Play
The transition from parallel play to associative play is gradual, not a clean switch. You’ll start to notice small moments of connection: one child handing a toy to another, brief eye contact followed by a smile, or a toddler copying what the child next to them just did and both of them laughing about it. These micro-interactions get longer and more frequent over time.
During associative play, children use the same toys and talk to each other, but they still have different goals. Two kids might both play in a toy kitchen, chatting and handing each other plastic food, but one is “making soup” while the other is “having a birthday party.” Full cooperative play, where children plan together and assign roles, typically arrives closer to age 4 or 5. Each stage builds directly on the comfort and observational skills that parallel play established. Children who have had plenty of relaxed, side-by-side play experiences tend to transition into these more complex social interactions with greater confidence.
