- Socioeconomic gaps in language development emerge early and can persist over time.
- Responsive conversations during daily routines help children learn new words and ideas.
- Books, songs, and stories offer accessible ways to support language development and strengthen bonds.
It’s 7:00 a.m. and María is preparing breakfast for her two-and-a-half-year-old son. As she pours his milk, she shows him a larger cup and a smaller one and asks, “Would you like your milk in the big cup or the small cup?” He points to the big cup. “The big cup, great! Let’s put your milk in the big cup so you can drink more milk and grow tall,” she replies. It may seem like an ordinary exchange, but María is helping her son develop something fundamental: language.
Language development begins long before children say their first words. From their earliest months, every response to a song, story, question, or answer helps build neural connections that support learning and help children understand the world around them.
Yet children do not all have the same opportunities to develop language. In Latin America and the Caribbean, socioeconomic gaps in language development appear in the earliest years of life and tend to persist over time. That is why the Inter-American Development Bank (IDB) works to strengthen interventions and projects that encourage frequent, warm, and responsive interactions between children and their caregivers.
In Ecuador, by age three, children from households in the poorest income quintile understand, on average, 31% fewer words than children from households in the richest quintile, according to data from the 2024 National Child Malnutrition Survey.
These early differences matter because language development in early childhood is an important predictor of later reading comprehension and academic performance.
Supporting language development from the earliest years is essential for children’s overall development and learning, and for narrowing gaps between children from lower- and higher-income households.
1. Talk to children from birth
Babies begin learning language long before they can speak. When an adult responds to their babbles, gestures, or sounds, they learn that communication goes both ways. Making eye contact, waiting for a response, and continuing the exchange help lay the foundations for language.
2. Build on what children say
A simple and effective strategy is to add to what children say. If a child points to a dog and says “dog,” an adult might respond:
“Yes, it’s a big dog, and it’s running.”
This introduces new words, ideas, and sentence structures without interrupting the conversation or turning it into a formal lesson.
3. Talk during everyday activities
Some of the best opportunities to support language development arise during ordinary activities: preparing meals, folding laundry, walking around the neighborhood, going to the market, or putting away toys.
During these moments, adults can name objects, describe actions, compare sizes, talk about colors, or ask questions. Families and caregivers can make the most of the time they already spend with children.
4. Read together and interact with books
Books are a powerful tool for enriching language. But reading together involves more than saying the words on the page. Adults can also:
- Point to pictures
- Name objects
- Ask questions
- Talk about what might happen next
- Connect the story to everyday experiences
For younger children, books featuring familiar objects and everyday situations are especially useful. As they grow, more complex stories can help them understand cause and effect and create stories of their own.
5. Share stories, songs, and oral traditions
Telling stories, singing songs, reciting rhymes, and talking about the day are practices found in virtually every culture. If there are no books at home, real objects or pictures in photographs, magazines, and other materials can also spark conversation.
These activities strengthen emotional bonds, enrich vocabulary, develop memory, and help children organize ideas and tell stories. They are simple, accessible ways to support language development in any setting.
Language develops day by day through everyday interactions at home, in childcare settings, and in the community. That is why the IDB works to promote high-quality interactions through family support programs, including home visits and group sessions, as well as initiatives that foster development through play.
