Understanding Language Development in Children Under 5
Supporting communication from first words to confident conversations
Language development is one of the most exciting (and sometimes surprising) parts of early childhood. From babbles and gestures to full-blown stories and “why” questions that never seem to end, children under five are constantly building the skills they need to communicate, connect, and learn.
At Sesame Lane, we understand that language development is about much more than learning words. It’s about relationships, confidence, emotional expression, and feeling understood. Whether your child is in nursery, toddler care, pre kindy or participating in a Government Approved Kindergarten Program in the year before school, supporting language development lays the foundation for lifelong learning.
What Is Language Development?
Language development refers to how children learn to understand language (receptive language) and how they use it to communicate (expressive language). This includes:
- Listening and understanding
- Speaking and forming sentences
- Vocabulary growth
- Non-verbal communication such as gestures and facial expressions
- Early literacy skills like storytelling, rhyming, and recognising sounds
Every child develops language at their own pace. Some children speak early, others take their time. Both can be completely typical.

Language Development by Age: What to Expect
Babies (0–12 months)
Language begins long before first words. Babies communicate through eye contact, facial expressions, touch, cooing, babbling, and responding to familiar voices. Talking, singing, and responding to your baby’s sounds helps build strong communication pathways in the brain.
Toddlers (1–3 years)
Toddlers experience rapid language growth. They begin using single words, then short phrases, and gradually combine words into simple sentences. This stage often includes repetition, mispronunciations, and a lot of enthusiastic storytelling.
Preschool & Kindergarten-Aged Children (3–5 years)
As children approach school age, language becomes more complex. Vocabulary expands, sentences grow longer, and children begin using language to explain ideas, express emotions, ask questions, and negotiate with others. This is a key focus of our Kindergarten Program, where language supports learning across all areas of development.
How the Kindergarten Program Supports Language Development
In the year before school, children enrolled in a Government Approved KindergartenProgram benefit from intentional, play-based learning experiences that support strong language and communication skills.
At Sesame Lane, our qualified early childhood teachers embed language development throughout the day by:
- Engaging children in meaningful conversations
- Reading books, telling stories, and encouraging storytelling
- Supporting vocabulary through play, routines, and real-world experiences
- Encouraging children to express ideas, feelings, and questions
- Building confidence to speak in group settings
These experiences help children develop the communication skills they need for a smooth transition to school, including listening, following instructions, and expressing themselves clearly.

The Role of Play in Language Development
Play is one of the most powerful tools for language learning. Through play, children experiment with words, practice conversations, and make sense of the world around them.
Pretend play, for example, helps children learn new vocabulary, take turns in conversation, and explore different roles and perspectives. Sensory play, outdoor play, music, and movement all provide rich opportunities for language to flourish naturally.
How Families Can Support Language Development at Home
Parents and caregivers play a vital role in supporting early language development. Simple, everyday interactions make a big difference:
- Talk with your child throughout the day about what you’re doing
- Read books together daily, even if it’s the same favourite over and over
- Ask open-ended questions and give children time to respond
- Sing songs, say rhymes, and play word games
- Listen with interest and validate your child’s attempts to communicate
Language grows best in warm, responsive relationships where children feel safe, heard, and encouraged.
When to Seek Support
Children develop language at different rates, but if you have concerns about your child’s speech or understanding, early support is important. At Sesame Lane, our educators regularly observe and monitor children’s development and work closely with families. If needed, we can help guide families toward additional professional support.
Language, Belonging, and Confidence
Strong language skills support more than learning, they help children build friendships, regulate emotions, and develop a sense of belonging. When children feel confident communicating, they are better equipped to navigate the world around them.
At Sesame Lane, we are passionate about creating environments where children’s voices are valued, their stories are heard, and their language development is nurtured every day.
