Understanding Your Child’s Communication Development (0–5 Years)
As parents, it’s completely natural to wonder if your child is “on track” with their communication. You might notice their first smile, their first word, or the way they point to show you something exciting and wonder what comes next.
The early years (0–5) are a time of incredible growth. In fact, the first three years are the most intensive period for speech and language development, as your child’s brain rapidly builds the foundations for communication.
This guide will help you understand what to look for across different areas of communication and when it might be helpful to seek support.
But First... What Do We Mean by “Communication”?
Communication is more than just talking. It includes:
Receptive language (understanding)
Expressive language (using words, sounds, or other ways to communicate)
Gestures (pointing, waving, showing)
Play skills (how children explore and interact)
Speech sounds (articulation) (how clearly words are said)
Engagement (connection, back-and-forth interaction)
All of these areas develop together and support each other over time.
0–12 Months: Building the Foundations
Before words begin, babies are already learning how communication works.
You might see:
Smiling, and back and forth interactions
Cooing and babbling (e.g. “ba-ba”, “da-da”)
Turning toward sounds and familiar voices
Responding to their name
Using gestures like reaching, pointing, or waving
Play & engagement:
Enjoys simple games like peek-a-boo
Shares attention with you (looking at you, then an object)
💡 These early “serve and return” interactions are the building blocks for later language.
1–2 Years: First Words & Understanding
This is often when parents hear those exciting first words.
Expressive language:
Says first words (e.g. “mum”, “ball”)
Begins to combine two words (e.g. “more milk”)
Vocabulary grows quickly over time
Receptive language:
Follows simple instructions (“give me the ball”)
Points to objects or body parts when named
Gestures & play:
Uses pointing to request and show
Starts pretend play (e.g. feeding a doll)
2–3 Years: Combining Words & Expanding Play
At this stage, communication really starts to take off.
Expressive language:
Uses 2–3 word phrases
Has around 50+ words
Starts asking simple questions
Receptive language:
Follows two-step instructions
Understands simple concepts (big/small, in/on)
Speech (articulation):
Speech is understood by familiar adults most of the time
Play & engagement:
More imaginative play (e.g. pretending with toys)
Begins interacting more with others
3–4 Years: Telling Stories & Being Understood
Children become more confident communicators.
Expressive language:
Uses longer sentences (4+ words)
Talks about experiences and daily events
Can be understood by unfamiliar people most of the time
Receptive language:
Answers simple questions (who, what, where)
Understands more complex instructions
Play:
Engages in imaginative and cooperative play
4–5 Years: Clearer Speech & Social Communication
By this age, children are preparing for school communication demands.
Expressive language:
Uses detailed sentences
Maintains conversations and topics
Communicates easily with others
Receptive language:
Understands stories and answers questions about them
Follows more complex instructions
Speech (articulation):
Most sounds are correct, with a few later-developing sounds still emerging (e.g. “r”, “th”, “s”)
Play & engagement:
Engages in cooperative play and friendships
When Should I Seek Support?
Every child develops at their own pace but we don’t recommend a “wait and see” approach if you have concerns.
It might be helpful to seek support from a speech pathologist if you notice:
Early signs (0–2 years)
Limited eye contact or interaction
Not responding to their name
Not using gestures (e.g. pointing, waving)
Not using words by around 12–18 months
Toddler & preschool years (2–5 years)
Difficulty understanding instructions
Not combining words by 2 years
Speech that is hard to understand for their age
Limited play skills or difficulty engaging with others
Frustration when trying to communicate
A Gentle Reminder
Milestones are guides, not strict rules. Some children develop earlier, some later, and many will fall somewhere in between.
But if something doesn’t feel quite right, you’re not overreacting. Early support can make a meaningful difference to your child’s communication, confidence, and participation in everyday life.
