Speech and language development is one of the most exciting aspects of a child’s early years—and one of the most varied. As parents, it’s natural to wonder if your child is “on track.” While every child develops at their own pace, there are key milestones that speech pathologists use to monitor communication growth.
This guide breaks down what to expect from birth through age five, helping you better understand how your child’s speech and language typically unfold.
0–6 Months: The Building Blocks Begin
Communication starts from day one. During the first six months, babies begin experimenting with sounds—cooing, gurgling, and crying in different pitches and patterns. These early vocalisations might seem simple, but they lay the foundation for speech by helping babies learn how to control their mouth, lips, and tongue.
You may also notice your baby squealing with excitement or quietening in response to your voice. These are all signs that they’re actively developing their listening and sound awareness skills.
“Early cooing and squealing are critical precursors to later speech and language development.”
(Eilers & Oller, 2020. Journal of Child Development)
7–12 Months: Babbling and First Words
Around this age, babbling becomes more speech-like. You’ll hear repeated consonant-vowel sounds such as “baba,” “dada,” or “mama.” While these may not always refer to the correct person, they show that your baby is learning the rhythm and flow of language.
By 12 months, many children say their first real word and begin to follow simple directions like “come here” or “give it to mummy.” They’ll also recognise their name and familiar words in daily routines.
12–18 Months: Growing Vocabulary and Meaningful Words
At this stage, toddlers typically say 5–20 recognisable words, often paired with gestures. Although pronunciation is still developing, their intentions become clearer. For example, “wawa” might mean “water,” and they may point while speaking to reinforce their message.
Children understand far more than they can express at this age, so it’s important to keep talking to them and labelling their world.
“Receptive language—what children understand—develops ahead of expressive language in the early stages of speech development.”
(Reznick & Goldfield, 2018. Journal of Speech, Language, and Hearing Research)
18–24 Months: Combining Words
This is a big leap forward. Most children begin combining two words to express thoughts and desires—such as “more juice” or “mummy go.” Their vocabulary grows rapidly to around 50+ words, and they start using early pronouns like “me” or “you,” even if incorrectly.
Your toddler may also begin identifying body parts and following simple two-step instructions, like “get your shoes and bring them here.”
2–3 Years: Early Sentences and Expanding Speech
By age three, most children are forming three- to four-word sentences, using basic grammar like plurals and past tense. Their vocabulary often exceeds 200–300 words, and they start to ask simple questions like “What’s that?” or “Where go?”
Speech intelligibility also improves—strangers can understand roughly half to three-quarters of what they say.
“Rapid vocabulary growth and emerging grammar are typical of the third year, with significant improvements in intelligibility.”
(Roy & Chiat, 2019. International Journal of Language & Communication Disorders)
3–5 Years: Full Sentences and Storytelling
Speech during the preschool years becomes far more complex. Your child will likely use sentences with five or more words, hold conversations, and begin telling short stories. Vocabulary can exceed 1,000 words by the age of five.
They’ll understand sequencing (first, then), follow multi-step directions, and use most grammatical structures. Sounds like “r,” “th,” and “l” may still be developing, which is entirely normal.
It’s also important to remember: there’s a wide range of what’s considered “typical.” Some children may hit milestones a bit earlier or later. What matters most is steady progress over time.
