Watching two toddlers attempt to play together can be illuminating and, at times, chaotic. Grabbing, parallel play with occasional collision, disputes over objects, and sudden departures from joint activity are entirely normal features of early social play. Understanding the developmental trajectory – when to expect what, and how to scaffold the learning – makes the chaos less frustrating and the progress more visible.
Healthbooq covers toddler development and social play through the early years.
The Development of Social Play
The classic framework for social play development was described by Mildred Parten at the University of Minnesota in 1932 and remains broadly applicable. Parten identified six stages of social play:
Unoccupied play (0-2 years): the child observes other children without joining in.
Solitary play (0-2 years): the child plays alone and independently.
Onlooker play (2-3 years): the child watches other children play, sometimes talking to them, without joining.
Parallel play (2-3 years): the child plays beside another child, using similar materials, without direct engagement.
Associative play (3-4 years): children play together with shared materials and activity, without a shared goal. There is interaction and communication, but roles and organisation are loose.
Cooperative play (4+ years): children play together with shared goals, organised roles, and clear structures (games with rules, collaborative building, joint dramatic play).
The transition from parallel to associative to cooperative play happens progressively and is influenced by social experience, language development, and the development of theory of mind (understanding others' perspectives).
Why Turn-Taking Is Hard for Toddlers
The ability to delay gratification – to accept "now you wait while she has a turn" – requires executive function capacities that are in very early stages of development at 2-3 years. The prefrontal cortex, which manages impulse control and delay of gratification, is not fully developed until the mid-twenties. Asking a 2-year-old to wait for a turn with a desired toy is asking them to override a powerful immediate impulse using cognitive machinery that barely exists yet.
This is why adult support is essential for early turn-taking: the adult's presence effectively "lends" executive function to the interaction while the child's own develops. Research by Adele Diamond at the University of British Columbia on executive function development has established these developmental timelines and the critical role of adult scaffolding.
How to Teach Turn-Taking
Make it physical. Ball rolling back and forth; taking turns on a slide; alternating moves in a simple stacking game – these involve concrete, obvious turn-taking without the emotional charge of sharing a beloved toy.
Narrate the turn. "It's your turn – now it's Maya's turn – now it's your turn again." Making the structure explicit helps toddlers follow it.
Keep wait times short. For 2-year-olds, a turn that lasts 5-10 seconds and then passes is more achievable than longer turns. As the child's capacity develops, turns can lengthen.
Model warmly. Parent and child turn-taking modelling (not just instruction) is the most effective teaching method. A parent who visibly waits their turn and says "my turn now!" with enthusiasm demonstrates the expected behaviour.
Separate "sharing" from "taking turns." Requiring a toddler to share a cherished toy is often developmentally inappropriate – it is asking the child to relinquish something with no guarantee of getting it back, which is a genuine sacrifice. Turn-taking (you get it back) is more achievable. Language that says "in two minutes it will be your turn" is more useful than "share."
Simple Games That Build Turn-Taking
Rolling a ball: back and forth between two children with an adult as mediator.
Tower building: each player places one block, then it is the other player's turn.
Parachute games: available at many toddler groups; explicit turn structure built in.
Simple matching games: pairs of cards laid face down; take turns to find matches (from about 3 years).
Ring and peg games: each player places one ring on the peg per turn.
Key Takeaways
Cooperative play – where children actively engage together toward a shared goal or within a shared game – develops progressively from parallel play (playing near but not with each other) beginning around 18-24 months to genuine cooperation around 3-4 years. Turn-taking, sharing, and negotiation skills do not come naturally at this age; they require consistent, patient modelling and scaffolding from adults. Early turn-taking is best taught through simple physical games rather than by making children share beloved possessions, which is often developmentally too demanding. The ability to delay gratification – to wait for one's turn – is a key developmental achievement that emerges across the toddler years.
