I’ve spent the better part of two decades staring at a blinking cursor or scribbling in the margins of picture book drafts, and if there’s one thing I’ve learned, it’s that writing for children is deceptively, almost unfairly, difficult. I can’t tell you how many times someone has found out what I do for a living and said, “Oh, I’ve got a great idea for a kid’s book, I just need to sit down for a weekend and knock it out.” People think that because the word count is low, the bar must be low, too. They think that because they can keep their own grandkids entertained during a rainy afternoon, they’ve got a bestseller in the bag.

But there is a massive, yawning chasm between a story that works in the cozy safety of a living room and a manuscript that can survive the cold, hard desk of an acquisitions editor.

The “mistakes” that actually sink a book usually have nothing to do with where you put a comma. They are fundamental misunderstandings of what a child actually wants. We get so wrapped up in the “message”, the thing we think they should learn, that we forget we’re writing for a tiny, discerning, and often brutal audience. If you bore a child, they don’t politely finish the chapter just to be nice. They just close the book, walk away, and go find a Lego. They are the only audience that will ghost you in person.

The “Vegetable” Story

The single most common mistake I see, and honestly, it lands on my desk every single week, is what I call the “Vegetable Story.” It’s that book written primarily to force-feed a lesson. You know the ones. The squirrel who finally learns to share his acorns, or the bunny who realizes, right on cue, that being honest is the best policy.

Here’s the thing: kids are smart. They can smell a lecture from a mile away, and they’ve got no patience for it. They get told what to do, how to sit, and when to be quiet all day long by parents, teachers, and coaches. When they finally sit down with a book, they’re looking for an escape, not another sermon disguised as a story.

I’ve had authors get pretty defensive when I tell them their moral is too heavy-handed. They’ll say, “But shouldn’t children’s books be educational?” And sure, in a sense, but that “education” needs to be a byproduct of a great story, not the engine driving it. If your character’s only reason for existing is to demonstrate a virtue, you don’t have a character. You have a puppet. And kids don’t connect with puppets; they connect with other messy, flawed beings.

The books that actually stay on the shelf for decades, the ones with the chewed corners and the taped-up spines, never start with a moral. They start with a character who wants something badly and fails spectacularly to get it. They start with mischief, or longing, or a mistake. If a kid learns something along the way? Great. But if the story doesn’t come first, the book won’t even make it past the first read.

The Problem of the Passive Protagonist

I was looking over a draft the other day where a little girl got lost in the woods, sat down to cry, and then, out of nowhere, a magical owl flew down to carry her home.

That isn’t a story; it’s a cop-out.

In this business, your protagonist has to be the one actually doing things. Even if the “inciting incident” is something they can’t control, they absolutely have to be the one to claw their way out of it. A huge mistake I see is writers letting an adult, or a convenient owl, or some lucky stroke of fate, save the day.

Why? Because kids have almost zero agency in the real world. They’re told when to wake up, what to eat, and when it’s time for bed. Books are the one place where they get to see someone their size taking charge. When a parent or teacher swoops in at the end to fix everything, you’re basically telling that child reader they’re powerless.

Let the kid be messy. Let them screw up. Let them solve the puzzle using their own weird, wonderful kid-logic. That’s where the real magic happens.

The Rhyme Trap

I might lose some friends over this, but someone has to say it: Stop trying to rhyme.

Unless you are a literal master of meter and scanned verse, your rhyming manuscript is probably standing in the way of your publication. Most amateur rhyme is “forced.” You end up choosing a word because it sounds like the last word, not because it’s the right word for the story.

I’ve seen authors change the entire direction of a plot just to make a stanza work with the word “blue.” It’s a trap. Poorly constructed rhyme is physically painful for a parent to read aloud. If the rhythm trips up the tongue, the book gets tossed.

If you absolutely must rhyme, you have to be obsessive about it. It isn’t just about the ending sounds; it’s about the stressed and unstressed syllables. It’s math. And if the math is off, the whole thing falls apart. Most of the time, the story would be ten times stronger if it were rewritten in prose. Prose allows you to be specific. Prose allows for nuance. Rhyme often forces you into clichés.

Writing “Down” to the Audience

There’s a certain “precious” tone some writers slip into that honestly makes me cringe. It’s that overly sweet, talking-down-to-them voice that treats children like they’re just not as smart as the rest of us.

But kids are incredibly sophisticated. They get irony, they love a bit of dark humour, and they can handle big, complicated emotions. Look at the icons: Sendak, Dahl, Blume. They didn’t feel the need to sugarcoat the world. They actually respected their readers.

If you’re leaning on “cutesy” words or dodging tough topics because you think a child can’t handle the truth, you’re probably missing the mark. You don’t need a thesaurus to impress them, but you do need the right words. If a character is frustrated, don’t just settle for “sad.” Are they indignant? Are they bewildered? Kids actually love discovering a big word when the story makes the meaning crystal clear.

The “Waiting for the Illustrator” Syndrome

In the picture book world, a massive blunder is over-writing the text because the author simply doesn’t trust the illustrations to do their job.

If your text says, “Billy wore a bright red hat and sat on the green grass,” and the art shows exactly that, you’ve just set your word count on fire. In a good picture book, the text and the art are in a marriage. They shouldn’t be repeating each other; they should be finishing each other’s sentences.

I’m always telling authors: look at your draft and ask what can be cut because the artist will draw it. The best picture books often have text that actually makes no sense without the pictures. That’s the “gap” where a child’s imagination really comes alive. If you describe every visual detail in the prose, you aren’t leaving any room for the illustrator to breathe, and you’re making the whole reading experience feel redundant.

The Lack of Stakes

I believe it is important to remember that you are battling not against books but rather iPad, video games, and ultra-fast-paced animated cartoons. In order to win, a book must offer one thing that those cannot give, a personal connection to the protagonist’s soul.

In short, when you learn to avoid these common mistakes, you won’t just be editing or fixing your manuscript. You’ll be letting it come through so that it can reach its intended audience. After all, wasn’t that always the point of the whole thing? Wasn’t this your goal from the start, to become the voice in a child’s head that continues on even after the lights turn off and they lie alone in their bed? It’s a tremendous responsibility. Of course, it’s also worth it.

A Word on Word Count

Let’s be real: publishing is a business, and businesses have standards that don’t care about your feelings. I see so many writers submit 2,000-word “picture book” manuscripts, and I just have to sigh.

In the current market, most picture books are under 500 words. Some are even under 300.

It sounds impossible, believe me, I’ve been there, until you realize that every single word has to earn its place. If a word isn’t moving the plot forward or revealing something deep about a character, it’s just clutter. Many writers get way too precious with their sentences. They fall in love with a specific description and refuse to cut it, even if it slows the story to a painful crawl.

You have to be ruthless.

Does this mean your story can’t have “voice”? No, not at all. But it means your voice has to be lean. Writing for children is the difficult art of saying the most while using the absolute least.

The Ending That’s Too Neat

From many acquisitions meetings, I can say that “happy ending” is usually a very boring ending. Kids intuitively understand that the life is not always giving out trophies and happiness simply because one has reached the end of a certain story. The children’s book, by its very nature, must bring hope and joy to readers, but such a feeling has to be achieved.

The second mistake I’ve noticed when working with children’s stories is “Instant Saint.” No matter how hard the protagonist has been for twenty pages of a text, he cannot change at once on page twenty-one and get an epiphany within three sentences. Such endings are not realistic at all. Real transformation happens gradually and often causes pain to the person who is going through it. In my opinion, the most memorable stories are those where external conflict remains unresolved but an internal one was resolved. Even if one failed the race, one finally understood that he likes the process of running. This makes a character real, believable, and memorable.

It must be noted that there is stiff competition from highly charged cartoons and video games with all sorts of instant flashing rewards. There is no chance that a book will beat those at that game. A book beats out its opponents with an intimate bond that connects the child to the soul of the character. By doing away with unnecessary clutter, we are opening the doors for children to see themselves in our stories. This is not just about making a clean manuscript; this is the sacred task of giving voice to what was in each of us as children.
