There is a video on YouTube. A Nigerian man named Samuel Asubiojo plays three characters in the same scene — a furious mother, a bewildered father, and a mischievous child. He switches between them in seconds, the costumes barely change, and the production value is roughly equivalent to filming in a sitting room because it was filmed in a sitting room.
It has tens of millions of views. Parents across West Africa, East Africa, and the diaspora report the same thing: their four-year-olds have watched it fifty times. They can recite the voices. They act it out in the kitchen.
Samuel Asubiojo made these videos for adults. His channel is called SamSpedy. He was not thinking about child development theory when he built his format. He was thinking about what makes Nigerian family dynamics funny.
The most-watched children’s show on earth in 2024
Bluey is an Australian animated series about a six-year-old Blue Heeler puppy and her family. It became the most-streamed programme in the United States in 2024—across all genres, not just children’s. More streamed than any drama, any sitcom, any reality show. In the same year, viewers in sixty countries and twenty languages watched it.
Parents do not merely tolerate Bluey. They recommend it to each other without their children present. Adults have been known to cry at seven-minute episodes nominally intended for toddlers.
Bluey’s production team drew explicitly on child development research. The show was built with an awareness of how children aged two to seven process stories, absorb emotions, and learn through play. It is, in a measurable sense, engineered for its audience. SamSpedy was not. And yet the children showed up for both.
What they have in common
I spent several months building a content analysis framework — the Child Appeal Index (CAI) — to measure, in quantitative terms, the structural features that make video content align with how young children’s minds actually work.
When I scored both Bluey’s and SamSpedy’s Mama Ojo formats against this instrument, they landed within four points of each other on a thirty-point scale. That gap is within the margin of a single scoring decision on a single dimension.
The format boundary—animated versus live action—produced no meaningful difference in child cognitive alignment. The cultural boundary—Australian institutional production versus Nigerian independent creators—produced no meaningful difference. The budget boundary—Disney-level streaming production versus a man with a camera in his sitting room—produced no meaningful difference.
The instrument was detecting something real: both pieces of content are structured almost identically for the same cognitive architecture.
How a two-year-old’s brain works (briefly)
Children between two and seven years old are in what developmental psychologist Jean Piaget called the preoperational stage. They process information through concrete, visible cause-and-effect sequences. They cannot handle multi-layered plots, inferred emotions, or unresolved ambiguity. They do not consider subtlety funny. What they find delightful, specifically:
Repetition. They view repetition not as a constraint, but rather as an enjoyable experience. When a schema is confirmed, the child’s brain produces a reward response. This explains why your three-year-old insists on watching the same episode for the fourteenth time and why you are feeling overwhelmed, despite their apparent contentment.
Exaggeration. According to the incongruity theory of humour, laughter happens when an expected pattern is violated in a non-threatening way. A parent reacting to minor misbehaviour with theatrical, disproportionate outrage is not threatening — it is performed, it is safe, it is incongruous. The child laughs because their schema of “this is the way a parent behaves” has been violated in a way that signals clearly: this is play.
Fast resolution. Conflict appears, chaos follows, situation resolves, scene resets. The whole arc in two minutes. Young children cannot sustain emotional investment in unresolved tension. They need the loop to close.
Visible emotions. No inference required. Every emotional state is performed at full volume, readable from across a room.
Narrative simplicity. One idea. One problem. One outcome. Predictable in the first five seconds.
Score these features across multiple dimensions and you get the Child Appeal Index. Both Bluey and SamSpedy score in the top band on nearly every dimension. The format is not relevant. The cognitive target is the same.
Why Bluey lasts and Cocomelon divides
But child appeal alone does not explain everything. Cocomelon—the YouTube juggernaut with billions of views, looping nursery rhymes, and flashing primary colors—scored even higher on child engagement than either Bluey or SamSpedy.
And yet parents despise it more than they despise Bluey. Paediatric researchers have flagged concerns about its editing pace. It generates a specific kind of parental fury that is almost cultural at this point.
The second index in our framework—the Parent Acceptability Index—explains this phenomenon. Cocomelon scores at the bottom of the entertainment content cluster on parent acceptability. Specifically, it scores 1 out of 5 on Stimulation Pacing (the content is clinically overstimulating by any reasonable measure) and 1 out of 5 on Adult Relatability (parents do not watch it independently; they endure it).
Bluey scores 5 on Adult Relatability. Adults watch it alone. They discuss it with other adults. They share episodes without their children present.
That is not a soft quality difference. It is a distribution mechanism. A parent who genuinely enjoys content does not merely permit their child to watch it — they become an active advocate for it. They recommend it to other parents. They share it on WhatsApp groups. They sustain it culturally across years in a way that algorithmic promotion alone cannot replicate.
Cocomelon achieves maximum child engagement by optimising in a precise direction that alienates adult co-viewers. It works commercially in the short term. It does not embed itself culturally the way Bluey has.
The educational gap is a single number
One of the more provocative findings from the scoring exercise involves educational content.
I scored a formal instructional video—the kind of alphabetic/phonics content that dominates YouTube Kids—against the same framework. It scored reasonably well on most dimensions: simple narrative, visual clarity, fast resolution, educational signal, and behavioural modelling. The one dimension that collapsed: Physical Exaggeration.
Score 1 out of 5. No theatrical performance, no slapstick, no disproportionate reactions. Just a calm teacher demonstrating letters at natural human register. This single dimension represents the structural gap between the content children are presented with and the content they demand.
Sesame Street solved this problem in 1969. They introduced the Muppets. Characters capable of unlimited physical and emotional exaggeration within an educational structure. The Muppets raised the exaggeration score of educational content dramatically without touching its educational architecture.
Independent African creators who have developed maximum Physical Exaggeration scores through entertainment content production represent an enormous, largely untapped resource for educational content in their own contexts. The format competency exists. What does not yet exist is the intentional application of that competency to educational goals.
What this means if you make content
If you are an independent creator anywhere — Lagos, Nairobi, Jakarta, São Paulo — and children are showing up for your content despite the fact that you did not target them, this framework explains why.
You have independently arrived at a content architecture that child cognition finds irresistible. You did not need a development research team. You needed audience feedback and enough iterations to converge on the format that works.
The question is whether you want to do something intentional with that convergence.
The Child Appeal Index gives you a diagnostic. Score your content against it. The dimension that is suppressing your child audience will be visible. The dimension that is suppressing parental advocacy will also be visible. These are often different dimensions, fixable through different format decisions.
The children were already there
The children who watch SamSpedy’s Mama Ojo videos on a shared family phone in Nairobi and the children who watch Bluey on a dedicated tablet in Sydney are doing the same cognitive thing.
They are finding, in content structured for their minds, the pleasures that their developmental stage makes available: the joy of predictability; the safety of exaggerated transgression; the satisfaction of a loop that closes cleanly.
The medium, the budget, the cultural context, and the production infrastructure are radically different. The experience — at the level that matters to a four-year-old — is the same.
That equivalence is invisible to platform categories, market classifications, and most existing research frameworks. It took a scoring instrument to make it measurable. But the children could already see it. They just kept pressing play.
