A cardboard box becomes a spaceship. A spoon becomes a microphone. To a tired parent at 6pm, it looks like nothing much. To a developing brain, pretend play is doing serious work, building language, self-control and empathy, often inside the same ten minutes.
Pediatricians have become unusually blunt about this. The American Academy of Pediatrics now advises doctors to write a prescription for play at well-child visits, on the grounds that it has been squeezed out of childhood by academic pressure and screens. Here is what the evidence actually says, and what it means at home.
What does pretend play actually build?
Pretend play strengthens executive function, the cluster of skills covering working memory, inhibitory control and cognitive flexibility, and it correlates with later academic performance in literacy and mathematics, according to the Child Mind Institute. It is not filler between naps. It is one of the main ways a young child practises thinking.
The AAP's clinical report "The Power of Play" goes further, describing play as a buffer against toxic stress and a driver of the parent-child relationship itself. When play and stable, nurturing relationships are both missing, the report warns, toxic stress can disrupt the development of executive function and prosocial behaviour.
Different kinds of pretending pull on different muscles:
| Type of play | What it looks like | Skills it exercises |
|---|---|---|
| Object substitution | A banana becomes a phone | Symbolic thinking, the root of language |
| Role play | Playing doctor, parent, shopkeeper | Empathy, perspective-taking, social scripts |
| Narrative play | Inventing and extending a story | Sequencing, complex grammar, memory |
| Sociodramatic play | Negotiating roles with another child | Self-regulation, conflict resolution |
| Small-world play | Figures, dolls, animals in miniature scenes | Planning, emotional rehearsal |
Does pretend play help with language?
Directly. When a child pretends a spoon is a hairbrush, they are using symbolic thinking, the same mental operation that lets a word stand for an object or idea. The American Academy of Pediatrics notes that make-believe boosts vocabulary and pushes children into more complex sentence structures.
Researchers have documented a specific pattern: children narrating pretend scenarios use more subjunctives, future tenses and adjectives than in ordinary conversation. "If the dragon were friendly, we would give him tea" is grammatically demanding, and children reach for it spontaneously when a story requires it.
Does it help with self-control and emotions?
It does, and this is where the research is most striking. Children who engage in more frequent make-believe play show better emotion regulation, and work described in Psychology Today links pretend play to reduced aggression and stronger delay of gratification.
The mechanism is intuitive once you see it. Pretending requires holding two realities at once, this is a stick and it is a sword, which is precisely the mental move behind impulse control: this is what I want and I am going to wait. Acting out a scared character or an angry dragon also gives children a rehearsal space for feelings they do not yet have words for.
Are children actually playing less?
Yes, measurably. Between 1981 and 1997, US children's playtime fell by roughly 25%, and children aged 3 to 11 lost about 12 hours of free time per week. Around 30% of American kindergartens now have no recess at all.
The AAP attributes the decline to a specific combination: more emphasis on academics, less free time for working parents and over-scheduled children, neighbourhoods where unsupervised outdoor play feels unsafe, and technologies that invite everyone to sit still and stare. Notably, it frames screens as one factor among four, not the sole villain.
How can parents encourage more of it?
The single most effective move is subtraction: protect unscheduled time and resist the urge to direct the scene. Beyond that, a few things reliably help.
What tends to extend pretend play:
- Open-ended props (scarves, boxes, blocks, figures) over single-function toys
- Following the child's storyline instead of correcting it
- Asking "what happens next?" rather than "what is that?"
- Leaving a scene set up overnight so play can resume
- Tolerating mess and boredom, because both are where the good stuff starts
The "what happens next?" habit is the same responsive back-and-forth that Harvard's Center on the Developing Child calls serve and return, the exchanges that shape brain architecture:
Does a child need special toys for this?
No, and the research points firmly the other way. The richest pretend play tends to come from simple, open-ended materials plus a responsive partner, not from elaborate or single-purpose toys. A child with a cardboard box and an interested adult will out-play a child with an expensive toy that does one thing on a loop.
That finding shaped how we built Ted: it invents stories and asks questions back rather than replaying scripted lines, so the child stays the author. We would rather be honest about the ceiling here, though. No product outperforms an adult who sits on the floor and plays along, and the AAP's recommendation is unambiguous that parent-child play is the gold standard. A responsive companion is for the hours when that is not on offer, not a replacement for it.
We have written about the related pull behind children's constant questions in the science of curiosity, why children attach so fiercely to simple companions in the psychology of comfort objects, and why empty afternoons are worth protecting in the case for boredom.
Frequently asked questions
At what age does pretend play start?
Simple pretending usually appears around 18 months, with elaborate role play and sustained storytelling developing between ages 3 and 6.
How much play should a preschooler get each day?
There is no official minimum, but the AAP recommends generous daily unstructured playtime and encourages pediatricians to prescribe play at well-child visits.
Can a child do too much pretend play?
Not in practice. Experts treat pretend play as beneficial in whatever quantity a child chooses, provided it is not displacing sleep, meals or real-world social contact.
Do stuffed animals count as pretend play props?
Yes, and they are among the best. Because a plush toy has no fixed script, children can cast it in any role, voice or story, which is exactly what open-ended play requires.
Is screen time the reason children play less?
It is one reason among several. The AAP lists academic pressure, over-scheduling and neighbourhood safety alongside screens, and the measured decline in playtime began well before smartphones existed.
