If you're waiting to hear your baby say that magical first word, you're not just being sentimental. You're paying attention to one of the most important developments of the early years. The good news is that teaching your baby to talk isn't about flashcards or drills. It's about the ordinary, loving moments you already share every day, shaped in a few simple ways that research shows really matter.
In this guide, we'll walk through a warm, concrete method you can start today. We'll cover how understanding comes before speaking, how to name the real objects in your daily routines, how back-and-forth "conversations" build your baby's brain, why reading real-photo books together helps, which first words are worth teaching first, and what's realistic to expect from roughly 6 to 18 months. Every step is grounded in real research, and none of it requires anything you don't already have.
One gentle note before we begin: this article is educational, not medical advice. Every child develops on their own timeline, and if you ever have concerns, your pediatrician or a speech-language pathologist is the right person to talk to.
Start With Understanding: Receptive Language Comes First
Here's something that surprises many parents: your baby understands words long before they can say them. This is the difference between receptive language, which is what your child comprehends, and expressive language, which is what your child can produce. Comprehension almost always comes first, and it builds the foundation everything else stands on.
The research on this is striking. In a well-known 2012 study published in the journal PNAS, psychologists Elika Bergelson and Daniel Swingley found that infants as young as 6 to 9 months already understand the meanings of many common words, especially names for foods and body parts. Long before they can form a single word themselves, babies are quietly mapping sounds to meanings.
What this means for you is freeing. You don't have to wait for your baby to talk back to start "teaching" words. Every time you name what your baby is looking at, touching, or eating, you're feeding that receptive vocabulary. The talking will come later, built on the understanding you're growing now.
A simple way to think about it: your job in these early months is to be a generous, patient narrator. You're not quizzing. You're describing the world in clear, repeated words so your baby can connect them to the things they see and feel.
How to nurture understanding day to day
Keep your language simple and repetitive. Use the real name for things ("that's your cup") rather than long, complicated sentences. Pause and give your baby time to look, respond, and take it in. Watch what your baby is already interested in, and name that. When you follow your child's gaze and attention instead of redirecting it, the words you offer land more easily, because your baby is already focused on the thing you're labeling.
Name Real Objects in Your Everyday Routines
You don't need a special "language time" carved out of your day. Your routines are the curriculum. Diaper changes, meals, bath time, getting dressed, and walks around the block are all rich opportunities to name the world, precisely because they repeat. Repetition is how young children learn, and routines hand you repetition for free.
The trick is to talk out loud about what's happening as it happens, using consistent words. At mealtime, name the foods: "banana," "spoon," "cup," "more." During a diaper change, name the body parts and actions: "wipe," "clean," "all done." In the bath, name what your baby touches: "water," "duck," "splash." Because these moments come around again and again, your baby hears the same words in the same context, which is exactly how meaning gets locked in.
Try to keep your words concrete and tied to something your baby can see or touch right now. Abstract talk washes over a young baby, but a word attached to a real, present object is something they can grab onto. When you say "ball" while holding the ball and rolling it, the word and the thing become one memory.
Make the words stick with a few small habits
- Say the word first and clearly, then use it in a short phrase: "Shoe. Let's put on your shoe."
- Repeat the same key words across the day so your baby hears them many times in familiar settings.
- Point to or hold up the object as you name it, so the word and the thing connect.
- Talk slowly and warmly, with a little extra melody in your voice. Babies are drawn to this sing-song style, often called parentese, and it helps them pick out words.
None of this has to feel like work. If narrating your day feels awkward at first, that's normal. Give it a week and it starts to feel like second nature, and you'll notice your baby watching your mouth, tracking objects, and lighting up at familiar words.
Turn Talk Into Back-and-Forth: Serve and Return
If there's one idea that changes how parents think about language, it's this: the magic isn't in how many words your baby hears. It's in the back-and-forth. Language grows fastest through conversation, even before your baby can say real words.
Researchers at the Center on the Developing Child at Harvard University describe this as "serve and return." Your baby serves by babbling, cooing, making a face, or reaching for something. You return by responding warmly, naming what they're focused on, and waiting for them to go again. These small exchanges, repeated thousands of times, are what shape the brain's architecture for communication.
A landmark 2018 study makes this concrete. Rachel Romeo and colleagues, publishing in the journal Psychological Science under the title "Beyond the 30-Million-Word Gap," found that the number of back-and-forth conversational turns a child experienced was linked to stronger activity in Broca's area, a part of the brain central to language. Notably, the conversational turns mattered more than the sheer number of words the children heard. It wasn't about talking at children. It was about talking with them.
Your baby can absolutely take a turn before they have words. A babble is a turn. A look is a turn. Reaching toward the dog is a turn. Your job is to notice the serve and return it, treating your baby as a real conversation partner.
How to build conversational turns with a pre-verbal baby
When your baby babbles, babble back, then pause and look at them expectantly, as if it's their turn again. When they make a sound or a face, respond as if they said something meaningful: "Oh, you like that? Tell me more." When they reach for or look at something, name it and wait: "The light! You see the light." That pause is doing quiet, important work. It teaches your baby that communication is a two-way rhythm, and it gives them the space to try again.
Over time, these turns get longer and more word-like. The babble becomes a sound that resembles a word, then a real word, then two words together. You're not just waiting for that to happen. Through serve and return, you're helping build it.
Read Together, Especially Real-Photo Books
Reading with your baby is one of the most powerful and enjoyable things you can do for language, and you can start long before your baby can sit still for a whole story. In the early months, "reading" might mean naming one picture per page, letting your baby chew the corner of a board book, or turning the pages together. That all counts.
What matters most isn't finishing the book. It's the interaction around it. A well-studied approach called dialogic reading, developed by researcher Grover Whitehurst and colleagues, flips the usual script: instead of you reading while your child listens, you invite your child to be an active participant. You ask questions, follow their interest, and build on what they say or point to. The U.S. Department of Education's What Works Clearinghouse has recognized dialogic reading as an effective approach for boosting young children's early language. With a pre-verbal baby, this looks like pointing and asking "Where's the dog?" and then celebrating when your baby looks or points, even without words.
The kind of book you choose can help, too. For babies and young toddlers, books with clear, realistic photographs of everyday objects have an advantage. Research on how children transfer learning from books to the real world suggests that very young children learn words and concepts more readily from realistic images than from cartoonish or highly stylized ones, because it's easier for them to connect the picture to the real thing it represents. Studies have also found that some flashy features, like touch-and-feel textures or pop-ups, can actually distract babies from the words on the page. Simple and real tends to win.
This is exactly the thinking behind our board book My First Words, which pairs clear, real-photo images of familiar objects with the kinds of high-frequency words babies encounter every day. It's designed to make naming, pointing, and back-and-forth reading easy, so the science we've been describing happens naturally as you turn the pages together.
A simple way to read with a baby
- Follow your baby's lead. If they want to stare at one page, stay there and keep naming.
- Name the picture, point to it, then pause to let your baby respond in their own way.
- Ask simple questions ("Where's the ball?") and warmly answer them yourself if your baby doesn't yet.
- Read the same books over and over. Familiarity is a feature, not a bug, and repetition is how the words sink in.
Choose "First Words That Matter"
When you're deciding which words to emphasize, it helps to be intentional. Not all words are equally useful to a new talker. The most valuable first words are the ones that are high-frequency, meaning your baby hears and can use them constantly, and functional, meaning they help your baby connect with you and get their needs met.
Think about the words that show up dozens of times a day in your baby's world: names of family members ("mama," "dada"), favorite foods ("milk," "banana"), key objects ("cup," "ball," "shoe," "book"), important people and pets, and powerful little social words like "more," "up," "hi," "bye," and "all done." These words give your baby real communicative power. A baby who can say "more" or "up" can influence their world, and that success motivates them to keep talking.
It's worth letting go of the pressure to teach an impressive-sounding vocabulary. A toddler who can say "elephant" but not "help" is less equipped than a toddler with a handful of everyday, functional words. Meaning and usefulness beat novelty every time. We wrote more about this in First Words That Actually Matter, and Why Most Word Lists Get This Wrong, which unpacks how to choose words that genuinely help your child communicate.
If you'd like a research-backed, ready-made list to work from, our First Words That Matter resource organizes early vocabulary around exactly these principles, so you can focus your energy on the words most likely to pay off.
What's Realistic by Age: Roughly 6 to 18 Months
Every baby moves at their own pace, and the range of normal is wide. Still, it helps to have a general map so you know what to look for and when. Here's a gentle picture of the first year and a half, drawing on guidance from the CDC and the American Speech-Language-Hearing Association (ASHA).
Around 6 to 9 months
This is the season of listening and understanding. Your baby is babbling, experimenting with sounds like "bababa" and "mamama," and, as the Bergelson and Swingley research showed, quietly beginning to understand the meanings of some everyday words. They may turn toward their name and respond to familiar voices. You likely won't hear true words yet, and that's completely expected. Your work now is all that naming and serve-and-return, filling the well that words will later be drawn from.
Around 9 to 12 months
Babbling starts to sound more like real speech, with strings of sounds that have the rhythm and melody of talking. Your baby may use gestures like pointing, waving, or reaching, which are important communication in their own right. Many babies say their first true word around their first birthday, often "mama," "dada," or a favorite object, though plenty of babies get there a bit earlier or later. Gestures and understanding are just as meaningful as spoken words at this stage.
Around 12 to 18 months
This is when spoken vocabulary usually begins to grow. According to CDC milestone guidance, many children say a word or two besides "mama" and "dada" around 15 months, and by 18 months are often trying to say several words and can follow simple directions like "give me the ball." The pace varies enormously from child to child. Some 18-month-olds have a handful of words, others have many, and both can be perfectly typical. What you generally want to see is steady progress: more understanding, more gestures, more attempts at sounds and words over time.
Try not to compare your baby to the child next door or to a chart on the internet. Milestones are averages, not deadlines. A baby who is understanding more, gesturing, babbling with intent, and engaging in back-and-forth is on a healthy path, even if the spoken words are taking their time.
When to Check In With a Professional
Because we never want this to be a source of anxiety, let's be clear and calm about it. Most late talkers catch up, and variation is the rule, not the exception. At the same time, you know your child best, and it's always okay to ask for reassurance.
It's reasonable to check in with your pediatrician or a speech-language pathologist if, for example, your baby isn't babbling or making sounds by around 9 months, isn't using gestures like pointing or waving by around 12 months, isn't understanding simple words or responding to their name, seems to lose skills they once had, or isn't saying any words by around 18 months. None of these on their own means something is wrong, but they're good reasons to have a conversation. Early support, when it's needed, is gentle and effective, and asking is never an overreaction.

Putting It All Together, Starting Today
Teaching your baby their first words isn't a program you have to master. It's a handful of loving habits woven into the days you already share. Understanding comes before speaking, so narrate generously. Routines are your best classroom, so name the real objects your baby sees and touches. Conversation matters more than word count, so treat every babble and glance as a turn. Reading together, especially with clear real-photo books, gives all of this a cozy, repeatable home. And when you focus on high-frequency, functional first words, you hand your baby real power to connect.
Pick one of these to start with today. Maybe it's narrating breakfast, or pausing to let your baby "answer" you, or reading one page of a photo book before nap. Small, consistent moments add up into a rich language environment, and your baby is learning from every one of them.
If you'd like tools that make this easy, our board book My First Words was built for exactly these moments, and it sits alongside the rest of our science-informed early-learning books on our series page. However you choose to begin, remember that the most powerful thing you can offer isn't a perfect method. It's your warm, attentive presence, one word at a time.
