Walk down the board book aisle and you'll see it everywhere: flaps to lift, tabs to pull, buttons that bark and moo, glittery patches to stroke, pop-ups that spring off the page. The word on the cover is almost always "interactive," and the promise is almost always the same. Books like these will help your toddler learn words faster. It's an appealing idea. If a plain book is good, a book that does things must be better.
Here's the honest answer, and it may surprise you. When researchers actually test these features, the gadgets often make word learning worse, not better. The flaps and buttons pull a young child's attention toward the book as a toy and away from the thing the book is trying to teach. That doesn't mean these books are bad or that you need to throw them out. It means the part of "interactive reading" that genuinely builds language isn't in the book at all. It's in you.
Let's walk through what the research shows, why it works this way, and how you can make almost any simple, realistic book truly interactive through the back-and-forth of reading together.
What "interactive" usually means, and why that's a problem
When a book is marketed as interactive, it almost always refers to physical features the child manipulates: lift-the-flap windows, pull-tabs that make a picture move, pop-ups, sound buttons, and touch-and-feel textures. These are sometimes called manipulative features. They're fun, and fun matters. But fun and teaching aren't the same thing, and a feature designed to delight isn't automatically a feature that helps a child map a new word onto a new object.
Young toddlers are still learning something adults take for granted: that a picture in a book stands for a real thing in the world. A photo of an apple represents an actual apple you can eat. That understanding, sometimes called symbolic insight, is fragile in the first couple of years. Anything that makes a book feel more like an object in its own right, something to poke and pull and squeeze, can quietly work against that insight. The child engages with the flap as a flap, not as a doorway to meaning.
This is the core tension. The features that make a book grabby are often the same features that keep a toddler's mind on the book rather than on the word.
What the research actually found
A handful of careful studies have tested manipulative books head to head against plain ones. The pattern is remarkably consistent.
Tare and colleagues, 2010: names that didn't transfer
In one well-known set of experiments, researchers read animal books to toddlers around 18 to 22 months old. Some children got a commercial manipulative version with flaps and pull-tabs. Others got a plain version of the very same book, with the interactive parts removed. Afterward, the children were tested to see whether they could recognize the animal names when shown new pictures and small real-world replicas.
The children who read the plain book generalized the names well. They could point to a new picture of the animal and to a little model of it. The children who read the flashy manipulative version performed no better than chance. In other words, the pull-tabs and flaps didn't just fail to help. They appeared to get in the way of the learning transferring beyond the page. In a follow-up with older toddlers learning simple facts (for example, what an animal likes to eat), children reading pop-up versions learned fewer facts than children reading plainer ones.
Chiong and DeLoache, 2012: the simple alphabet book won
A similar story shows up with letters. Researchers compared how well young children learned letters from an alphabet book that had manipulative features, such as pieces to pull and textures to touch, versus a simplified alphabet book without them. The children learned more letters from the simple book than from the manipulative one. The researchers suggested the interactive elements made the book more object-like, competing with its job as a symbol that points to letters and sounds.
Flack and Horst: one clear image at a time
A related line of work looks at visual clutter rather than moving parts, and it points the same direction. When children were read storybooks that introduced new words, they learned those words better when they saw a single illustration at a time rather than two images competing for attention on a spread. Less on the page meant more in the child's vocabulary. The takeaway generalizes nicely: a clean, focused page helps a toddler know exactly what a new word refers to.
Touch-and-feel textures got the same result
More recent work has tested the touch-and-feel format specifically, the kind of "first words" board book with a fuzzy patch on the puppy and a rough patch on the lion. In these studies, infants learned words less well from the touch-and-feel versions than from matched books without the texture patches. The tactile feature drew little hands and attention to the texture itself, not to the picture and its name.
Put these findings together and a clear message emerges. Across pull-tabs, pop-ups, sound buttons, touch-and-feel patches, and busy pages, the extra stuff tends to compete with the word. For the specific goal of learning new vocabulary, simpler and more realistic usually wins.
Why gadgets pull attention the wrong way
None of this means toddlers aren't paying attention. They're paying close attention, just to the wrong thing for the purpose of word learning. A few reasons this happens:
- Divided attention. A toddler has a limited pool of attention. Every flap and button is one more thing to notice, and each one competes with the picture and the word you're saying. When the book asks a child to do a lot, the word can get lost in the busyness.
- The book becomes the toy. Manipulative features invite a child to treat the book as an object to operate. That's lovely for play, but it nudges attention away from the symbolic work of "this picture means that real thing."
- Weaker transfer. Learning a word only counts when a child can use it beyond the page: pointing to the family dog after seeing a dog in a book. Studies show that clean, realistic images support this transfer, while manipulative and busy formats often don't.
This connects to a broader theme in early vocabulary research: what a child learns first is shaped by clarity and relevance, not novelty. If you want to go deeper on which words matter most and why the usual word lists often miss the mark, we wrote a companion piece on first words that actually matter.
The interaction that actually helps is the conversation
Here's the reframe, and it's genuinely good news. The most powerful interactive feature in any reading session isn't printed on the page. It's the back-and-forth between you and your child. Decades of research on shared book reading point to the same conclusion: the quality of the conversation around the book predicts language growth far more than the bells and whistles in the book.
The best-studied version of this has a name: dialogic reading. Instead of reading straight through while your child listens, you turn reading into a dialogue. You ask, you wait, you build on what your child says. Reviews of dialogic reading, including a summary from the What Works Clearinghouse across multiple studies of preschoolers, found positive effects on children's oral language. The shift is simple: the child moves from passive listener to active teller, with you scaffolding along the way.
Researchers often describe the pattern with the sequence PEER:
- Prompt your child to say something about the page. "What's the doggy doing?"
- Evaluate the answer warmly. "Yes, he's running."
- Expand on it just a little. "The big brown dog is running fast."
- Repeat the prompt so your child can try the fuller version. "Can you say the dog is running fast?"
You don't need to memorize a script or do this on every page. Even a few real exchanges per book change the reading from a one-way broadcast into a genuine conversation, and that conversation is where words take root.
How to make any simple book truly interactive
You already have everything you need. A plain, realistic picture book plus your voice and attention beats a gadget-filled book you read on autopilot. Here are practical ways to bring the interaction, using conversation rather than mechanics.
Point and label, then pause
Put your finger on the picture and name it clearly: "Cup." The pointing links the word to the image, and the pause gives your child room to look, process, and maybe repeat. That small silence does a lot of work. You're not filling every second; you're leaving space for your child to join in.
Ask, don't just tell
Turn statements into invitations. Instead of narrating every page, ask "Where's the ball?" or "What sound does the cow make?" Questions pull your child into the driver's seat. For very young toddlers, start with pointing questions ("Where's the baby?") and grow into open ones ("What's happening here?") as language develops.
Follow your child's lead
If your toddler is stuck on the truck for three pages, stay there. Talk about the truck, its wheels, its color, where it might be going. Interest is the fuel for attention, and attention is where learning lives. You don't have to finish the book, and you certainly don't have to read the words in order.
Repeat, and welcome the same book again
Toddlers learn words through repetition, and hearing the same word in the same clear context over several readings helps it stick. The hundredth reading of a beloved book isn't a waste. It's exactly how young brains consolidate vocabulary. Lean into the requests to read it "again."
Connect the page to real life
When the book shows a banana, mention the banana your child ate at breakfast. When it shows a dog, talk about the neighbor's dog. These little bridges between book and world are precisely the transfer that studies show matters most, and they help a word become truly usable.
Keep the pictures clear and the words within reach
For teaching new words, choose books with clean, realistic images, ideally one clear subject at a time, and words drawn from your child's everyday life. This is the thinking behind our own titles, like My First Words and First Words That Matter, which keep each page focused on a single real object so the word has nowhere to hide. You can see how the whole approach fits together across our book series.
So are flap and sound books bad?
No. And this is where balance matters. Lift-the-flap books, sound books, and touch-and-feel books are wonderful for a lot of things. They build the sheer joy of books, which keeps children coming back to reading. They support fine motor skills as little fingers lift and pull. They spark curiosity and delight, and a child who loves books is a child who will read more of them. Those are real, worthwhile benefits.
The point is narrower than "avoid these books." It's this: the specific job of teaching a brand-new word is done better by a simple, realistic image paired with a rich conversation. So think of your bookshelf as having two kinds of books doing two different jobs. The gadget books are for play, motor practice, and fun. The clean, realistic books are your best teaching tools when you want to grow vocabulary. There's room for both, and neither has to do the other's job.
A practical way to hold this: when your goal is a giggle and a game, reach for the pop-up. When your goal is helping "cup" or "dog" or "shoe" become a word your child actually uses, reach for the simple book and bring the conversation.
What to watch for, and when to check in
Every child follows their own timeline, and there's a wide, normal range for when words arrive. Reading together, in the conversational way we've described, is one of the most supportive things you can do, but it isn't a test your child can pass or fail. Some toddlers soak up words early; others build a quiet foundation and then bloom. Both can be perfectly typical.
That said, it helps to know the general milestones so you can enjoy the journey without second-guessing every quiet week. If you'd like a clear, calm map of what tends to happen when, and the signs that are worth a conversation with your pediatrician or a speech-language pathologist, our Speech Development Guide lays out milestones, everyday activities, and genuine red flags in one place. It's meant to give you confidence and clarity, not worry.
One honest note: this article shares what the research says about books and word learning, and it isn't a substitute for medical advice. If you ever have concerns about your child's hearing, speech, or overall development, trust your instincts and reach out to a professional. Early support is always worthwhile, and asking is never an overreaction.
The takeaway
The books that help toddlers talk aren't the ones that do the most. They're the ones that get out of the way so a clear picture, a clear word, and a warm conversation can do their work. The research is refreshingly consistent: manipulative features like flaps, pop-ups, sound buttons, and touch-and-feel patches tend to pull attention toward the book as a toy and away from the word, while simple, realistic images support the kind of learning that transfers to real life.
The genuinely interactive part of reading has been with you all along. It's the pointing, the asking, the pausing, the following your child's lead, and the joy you share turning pages together. Keep the flap books for fun. Keep the simple books close for teaching. And keep talking. That conversation, more than anything printed or pull-tabbed, is what helps your toddler find their words.
