Why Early Language Development Matters

Almost 8 years ago, I was you. I was a mom who was petrified of “messing up” my child’s development. I didn’t know how to support my babies language development. But then I became a speech and language pathologist. As a pediatric speech-language pathologist and a mom, I’ve now seen firsthand how small, consistent interactions can make a huge difference in a child’s communication trajectory. The first few years of life are a time of extraordinary brain growth, neural plasticity, and sensitivity to language input.

Did you know that research shows that babies begin listening to the sounds of language even before birth? And from day one they’re absorbing patterns of speech and communication cues. The more “serve and return” interactions they have—where a caregiver responds to their sounds, gestures, and expressions—the more robust their neural wiring for language becomes.

In one classic study, infants who heard more child-directed speech (speech directed specifically to them) became more efficient in processing familiar words, and by 24 months had larger expressive vocabularies than peers who heard less child-directed speech. Another longitudinal study found that the quantity and quality of early language input correlates with later language outcomes.

All this means: the everyday speech, narration, smiles, and responses you give your child matter. They aren’t “just playing”—they’re wiring their brain for language.

Early Language Development Milestones in the First 3 Years

To know what to support, it helps to know what kinds of language growth are expected in babies and toddlers. These are guidelines, not rigid rules—but they help us see patterns and know when additional support might be needed.

Below is a simplified overview of receptive (understanding) and expressive (speaking) milestones in the first three years:

Everyday Routines That Encourage Early Language Development

Listen, we are all too busy to add “one more thing” to our already crammed schedules. One of the beauties of supporting language is that you don’t need a special “lesson time.” You can weave language-rich interactions into your daily routines. Here are some ways I do it with my kids.

Talking during feeding

Feeding times (bottle, breast, solids) are natural moments for one-on-one attention. Try these:

• Narrate what you’re doing: “I’ve got your spoon. I’m getting your yogurt. Yum, Yum that’s good”
• Pause and wait for your baby’s sounds or gestures before continuing—this teaches turn-taking.
• Use varied intonation, exaggerated prosody, and “parentese” (slower speech, higher pitch) to accentuate words.
• Name what your baby looks at or what you’re offering: “Here’s the banana. Yellow banana in your bowl.”

Narrating play

Play is the “work” of babies and toddlers—and a goldmine for language. I admit, I don’t love playing kid games. It can be hard for me to get on their level and focus on their interests. But, it is worth it to see their language develop. So, if you are like me and this is a struggle, here are a few tips:

• Commentate what your child is doing: “You grabbed the truck. The truck is red. You’re pushing the wheels.”
• Follow their lead: If they pick up a block, talk about that block, its color, shape, what it can do.”You have blue block, let’s stack blocks, your block, my block, all done block”.
• Introduce new vocabulary in context: E.g. “See the big, bumpy ball?” You introduce the word “bumpy” using a toy your child can physically touch and feel in that moment instead of reading about it in an abstract book
• Pause for responses: After you say something, wait several seconds for them to respond (I often count to 5 in my head before I say anything else)
• Narrate actions (“You’re climbing up,” “Let’s slide down”) to link language to movement.

Reading daily

Reading is one of the most powerful tools in your language-support toolkit.

• A recent study (at Marshall University) found that consistent parental reading during the first year improved infants’ language scores. Read that study here.
• Read books with simple, repetitive language, and point to pictures as you name them. Here is an article that talks about specific books to read at home.
• Pause to ask questions or encourage your child’s participation (“Where’s the dog?”).
• Use dialogic reading: instead of just reading, interact—ask the child to point, name, or talk about the picture as you are reading.
• Over time, expand to more complex books and stories, but even a few minutes daily helps expose your child to new language and vocabulary.

By combining talk during feeding, talk during play, and daily reading, you create a rich, reinforcing environment for early language.

When to Be Concerned

You know your child best, and as a mom-SLP I want to empower you with red flags If you notice any of these persisting, it’s worth talking to your pediatrician or a speech-language pathologist: And remember, none of this is medical advice!

• By 12–18 months: very few or no recognizable words, or gestures like pointing are absent
• By 18–24 months: fewer than 20–30 words, or not combining two words
• Persistent difficulty understanding simple instructions
• A regression (loss) of any communication behaviors
• Significant difference between understanding and expressing (e.g. child seems to understand very little)
• Consistently not pointing, gesturing, imitating, or attending to communication
• Concerns about hearing (ear infections, inconsistent responses to sound)

Early monitoring and intervention are key. The earlier a delay is identified, the more effective support often is.

Final Thoughts (A Note from One Mom to Another)

When I look back on my journey as a pediatric SLP mom, I remember the times I felt inadequate—wondering whether I was doing “enough” to help my kids learn language. But over time I came to see that it’s not magic or huge interventions that matter most—it’s consistency, responsive love sprinkled with evidenced based interventions, and small moments stitched together day by day that created the most growth.

If you speak to your child, respond to their babbles, narrate your world together, and read often, you’re giving them one of the greatest gifts: the foundation of language. It doesn’t matter if some days feel slow or uncertain—those little interactions add up in powerful ways.
