Have you ever noticed how your voice naturally changes when you talk to your baby or toddler? That sing-song, melodic way of speaking—with its higher pitch, slower pace, and exaggerated expressions—isn't just adorable. It's actually one of the most powerful tools you have to support your child's language development. Researchers call this special way of speaking "parentese," and it turns out that parents around the world have been instinctively doing something remarkable for their children's brains.
At Runningbrook International Preschool, we've been supporting families from over 35 countries since 1993, and we've seen firsthand how language flourishes when children are surrounded by rich, responsive communication. Whether you're raising your child in a bilingual environment or navigating multiple languages at home, understanding parentese can help you feel confident that every conversation you have with your little one is building their cognitive foundation.
In this article, we'll explore what parentese is, why it matters for early childhood development, and most importantly, what you can do to harness its benefits—no matter your child's age or the languages you speak at home.
Parentese (sometimes called "infant-directed speech" or "child-directed speech") is the instinctive way adults modify their speech when talking to babies and young children. It's characterized by:
Importantly, parentese is NOT the same as "baby talk," which involves using made-up words or incorrect grammar (like saying "widdle" instead of "little"). Parentese uses real words, proper grammar, and correct pronunciation—just delivered in a more engaging, attention-grabbing way.
Research from the University of Washington's Institute for Learning & Brain Sciences has shown that parentese activates the language centers in babies' brains more effectively than regular adult speech. In a landmark 2020 study, researchers found that coaching parents to use more parentese led to measurable improvements in children's language skills, with babies producing 50% more words by age 18 months compared to control groups.
Understanding what's typical at each stage can help you recognize the amazing progress your child is making. Remember, every child develops at their own pace, and there's a wide range of "normal" when it comes to language milestones.
During this foundational period, you might notice your child:
At this exciting stage, language often seems to explode. You might observe:
As children approach school age, their language becomes increasingly sophisticated:
If you ever have questions about your child's language development, remember that you are the expert on your own child. Trust your instincts, and don't hesitate to reach out to your child's educators or healthcare provider if something feels off.
The beautiful thing about parentese is that you're probably already using it naturally. Here are some ways to be more intentional about this powerful communication tool:
When you talk to your child, try to get down to their level and make eye contact. Your facial expressions, lip movements, and animated features all provide important visual information that helps children connect sounds with meaning.
Try this: During diaper changes, mealtimes, or quiet moments, put away distractions and have a "conversation" with your baby—even before they can respond with words. Narrate what you're doing, ask questions, and pause to give them time to "answer" with coos, babbles, or gestures.
When introducing new vocabulary or concepts, speak a bit more slowly and put extra emphasis on important words. This helps your child's brain identify where one word ends and another begins—a crucial skill for language learning.
Try this: Instead of quickly saying "Let's put on your shoes," try "Let's put on your SHOES! These are your red SHOES. Can you help me with the SHOES?" The repetition and emphasis help cement the new word in your child's memory.
Pay attention to what captures your child's interest, then talk about it. This child-centered approach—where communication follows the child's natural curiosity—is far more effective than trying to direct their attention to what you want to discuss.
Try this: If your toddler is fascinated by a bird outside the window, join them in their wonder. "You see the BIRD! What a beautiful bird. The bird is flying. Fly, fly, fly! Where do you think the bird is going?"
When your child says something, respond by expanding on it. This technique, called "recasting," models correct grammar and introduces new vocabulary without directly correcting your child.
Try this: If your child points to a dog and says "Doggy run!" you might respond, "Yes! The doggy IS running! The brown doggy is running so fast. He looks happy, doesn't he?"
If your family uses more than one language, you might wonder whether parentese works the same way in each language. The answer is yes! Research shows that parentese exists across cultures and languages, and using it in both languages supports bilingual development.
Try this: Use parentese consistently in whichever language feels most natural to you. If you speak Spanish at home and English at school, use your warm, engaging parentese voice in Spanish during family time. Your child's brain is remarkably capable of learning multiple languages simultaneously, and your enthusiastic, loving communication in any language is building their linguistic foundation.
At Runningbrook, we celebrate the rich diversity of languages and cultures represented in our community. Our educators understand that families may have different communication styles influenced by their cultural backgrounds, and all of these approaches have value.
Some cultures emphasize more direct instruction, while others favor learning through observation and participation. Some families are naturally more expressive vocally, while others communicate more through physical closeness and nonverbal cues. There's no single "right" way to support your child's language development.
What research consistently shows is that responsive, loving communication—where caregivers pay attention to children's cues and respond warmly—supports language development across all cultures. Whether you use dramatic parentese or a quieter, gentler approach, the key ingredients are connection, attention, and genuine engagement.
Language doesn't develop in isolation—it flourishes through meaningful interactions and play-based learning. When children are engaged in play they find interesting and enjoyable, they're naturally motivated to communicate.
In our programs at Runningbrook, from our youngest learners in Growing Steps to our Pre-Kinder students preparing for primary school, we create environments rich in language opportunities:
Our child-centered approach means that educators follow children's interests, using their natural curiosity as a springboard for rich language experiences. When a child discovers a caterpillar on the playground or becomes fascinated with building towers, those moments become opportunities for vocabulary building, question-asking, and meaningful conversation.
Every time you speak to your child—whether you're narrating your grocery shopping trip, reading a bedtime story, or simply chatting during breakfast—you're shaping their brain and building their language abilities. The warm, engaging way you naturally speak to your little one isn't just instinct; it's one of the most important gifts you can give them.
Remember, you don't need special training or expensive programs to support your child's language development. You just need to talk, listen, and connect. Trust yourself. You know your child better than anyone else, and your loving presence is the foundation upon which all their learning is built.
At Runningbrook International Preschool, we're honored to partner with families in supporting children's growth and development. If you have questions about your child's language journey or would like to learn more about our bilingual, child-centered programs, we're always here to help.
Keep talking, keep singing, keep reading, and keep connecting. Your voice is magic to your child.
