When we talk about writing children in fiction, we tend to focus on the sweet stuff: their innocence, their boundless curiosity, their emotional vulnerability. These are the traits that tug at readers’ hearts and make young characters feel tender and precious. But there’s one crucial aspect of childhood that often gets swept under the rug—annoyance. Writers frequently avoid it, worried that an irritating child character will alienate readers. Yet the truth is, children are annoying. They interrupt at the worst times, ask endless questions, repeat themselves, act on impulse, and push boundaries just to see where they are. It’s not a flaw—it’s development in motion.
In fact, those moments of irritation are exactly what make child characters believable. Their unpredictability, their noise, their refusal to behave like mini-adults is what gives them dimension and realism. In this piece, I explore why a little annoyance goes a long way when writing children—and how leaning into it can transform a flat character into one who feels genuinely alive.
Annoyance is not a flaw to fix, but a necessary ingredient for believable child characters. Often, it’s subtle—something you only recognize after stepping back—but how you shape this trait can deeply affect whether the character is endearing or unbearable to readers. From loud, brash protagonists like Naruto to the quietly mischievous Greg from Over the Garden Wall, a child’s ability to get under our skin is part of what makes them human—and sometimes, endearing.
Take Naruto from the series of the same name—a loud, brash 12-year-old aspiring for greatness. On the annoyance scale, he ranks near the top, just below characters like Asta from Black Clover. His obnoxious catchphrases, constant shouting, and reckless behavior are enough to turn some viewers off completely. But for those around his age, he’s often relatable. Like many preteens, Naruto believes he’s invincible. His need for attention, born from being ostracized for hosting a demon inside him, explains his outbursts. Still, even with his tragic backstory softening some of his brash characteristics, his neon orange jumpsuit and over-the-top antics remain divisive. He was written for kids—but not everyone enjoys him, including some kids.
In contrast, Greg from Over the Garden Wall embodies a different kind of annoyance—one that’s more whimsical than grating. His relentless cheerfulness, bizarre logic, and impulsive actions (like throwing away the very coins they need to escape) could easily become irritating. Yet, he’s so genuine and good-hearted that his mischief feels more charming than frustrating. The only character consistently bothered by Greg is his older brother, Wirt—who, conveniently, represents the “straight man” figure, and maybe even us as the audience.
Wirt, likely around 13 or 14, tries hard to be mature but frequently slips into childish blame-shifting and dramatics. He wants to be seen as grown-up, yet often acts just as immature as Greg in subtler ways. His anxious, poetic brooding makes him feel like the classic “older sibling” archetype—trying to keep control, scared out of his depth, but also deeply caring. His flaws round him out and keep his own annoying tendencies grounded in reality.
Then we have a more unusual example: Charlie from Tim Burton’s 2005 adaptation of Charlie and the Chocolate Factory. Unlike the 1971 version, this Charlie is nearly saint-like. He’s selfless, mature, and even refuses to keep the golden ticket in hopes of helping his family. Gone is the impulsiveness of drinking Fizzy Lifting Drinks. This Charlie is pure, polite… and not all that believable as a real kid. By scrubbing out the typical childhood annoyances, the film loses a vital sense of authenticity. He feels less like a person and more like a moral ideal.
On the more realistic end of the spectrum, you have Steven Universe. In the early seasons, Steven’s mild annoyances are subtle but consistent—pestering adults with repeated questions, offering unsolicited help, or pushing others to join his activities even when they’d rather not. These are exactly the kinds of small, persistent irritations you find in actual children.Yet, because they’re grounded in genuine curiosity and kindness, they come across as relatable instead of exhausting.
The truth is: children are annoying. They interrupt, they repeat themselves, they don’t always listen—and that’s exactly why they feel real. A child character without any of these traits quickly becomes too polished, too perfect. A saint. And saints, as we know, are hard to relate to.
So, when writing child characters, don’t erase the annoyance—embrace it. Use it wisely. Just enough to remind the reader that they’re kids, still learning, still rough around the edges. That touch of irritation makes their joy, growth, and vulnerability all the more compelling.
