Speech Development Milestones — When Should My Toddler Be Talking?

Reading time: 8 minutes

If you have ever found yourself Googling "when should my toddler be talking" at 11pm, you are not alone. Speech development milestones are one of the most common concerns for Australian parents, and it is completely natural to compare your child's language to others their age.

The truth is that speech and language development varies enormously between children. Some toddlers are chatting in sentences by 18 months while others are still pointing and grunting well past two. Both can be perfectly normal. But understanding the general milestones — and knowing when to seek help — gives you the confidence to support your child's communication journey.

Understanding the Difference: Speech vs Language

Before we look at milestones, it is important to understand two different things:

Speech refers to the physical ability to produce sounds and words. It is about articulation, fluency, and voice.

Language refers to the ability to understand and use words to communicate. It includes receptive language (what your child understands) and expressive language (what your child says or communicates).

A child can have strong language skills but unclear speech, or clear speech but limited vocabulary. Both are important, and they develop somewhat independently.

Speech and Language Milestones by Age

These milestones are based on guidelines from Speech Pathology Australia and the Raising Children Network. Remember, these are general guides — there is a wide range of normal.

0-6 Months

Startles at loud sounds
Coos and makes vowel sounds ("aah," "ooh")
Turns toward voices and sounds
Begins to babble with consonant sounds ("ba," "ma")
Laughs and squeals
Makes different cries for different needs

6-12 Months

Babbles with varied sounds ("bababa," "mamama," "dadada")
Responds to their name
Understands "no" and simple instructions with gestures
Points to things they want
May say first words ("mama," "dada," "bye-bye") around 12 months
Uses gestures like waving and clapping
Imitates sounds and actions

12-18 Months

Says 6-20 words (though these may not all be clear)
Understands more words than they can say (receptive language is ahead of expressive)
Points to familiar objects when named ("Where's the dog?")
Follows simple instructions ("Give it to Mummy")
Tries to copy words
Uses gestures alongside words
May use "jargon" — babbling that sounds like conversation with intonation and rhythm

18-24 Months

Uses 50+ words
Begins combining two words ("more milk," "Daddy go," "big truck")
Follows two-step instructions ("Pick up the ball and give it to me")
Points to body parts when asked
Uses words to express needs rather than just crying or pointing
Strangers can understand about 50 percent of what they say
Asks simple questions ("What that?")

2-3 Years

Uses 200-1000+ words
Speaks in sentences of 3-4 words
Asks "why" and "what" questions (prepare yourself)
Can be understood by strangers about 75 percent of the time
Uses pronouns (I, you, me, mine)
Follows multi-step instructions
Engages in simple conversations
Talks about things that happened in the past
Begins to use plurals and past tense

3-4 Years

Speaks in sentences of 4-6 words
Tells simple stories
Can be understood by strangers most of the time
Asks lots of questions
Understands concepts like "same" and "different," "big" and "little"
Uses grammar more accurately (though errors are still normal and expected)
Enjoys rhyming and word play

When Should You Be Concerned?

While there is a wide range of normal, Speech Pathology Australia recommends seeking professional advice if your child:

By 12 months: Is not babbling, not using gestures (pointing, waving), or not responding to their name
By 18 months: Has fewer than 6 words, does not understand simple instructions, or has lost words they previously used
By 2 years: Uses fewer than 50 words, is not combining two words, or cannot be understood by familiar people
By 3 years: Is not using sentences, cannot be understood by strangers, or is becoming frustrated by their inability to communicate
At any age: Loses language skills they previously had (this warrants immediate attention)

If you have a gut feeling that something is not right, trust it. Early intervention for speech and language delays is incredibly effective. In Western Australia, you can access support through:

Your GP — for a referral to a speech pathologist
Child Development Service WA (formerly Child Development Centres) — free government-funded assessments
Private speech pathologists — many in the Perth metro area, some with shorter wait times
Telethon Kids Institute — research and resources on child development

What Causes Speech Delays?

Speech and language delays can happen for many reasons, and often there is no single cause:

Hearing issues — even mild or temporary hearing loss (like from recurrent ear infections, which are very common in WA's climate) can impact speech
Developmental factors — some children are simply later talkers who catch up on their own
Environmental factors — limited exposure to conversation and language-rich environments
Multilingual homes — children learning two or more languages may appear "slower" initially but are actually developing multiple language systems simultaneously (this is not a delay)
Developmental conditions — autism spectrum, intellectual disability, or specific language impairment may affect speech and language

8 Ways to Support Your Toddler's Speech at Home

Talk constantly. Narrate your day: "Now we're putting on your shoes. One shoe... two shoes! Let's go to the car." This floods your child with language.
Read together every day. Books are one of the most powerful language-building tools. Point to pictures, ask questions, and let your child turn the pages.
Follow their lead. If your child is interested in the dog, talk about the dog. Language grows fastest when it is connected to something the child is already engaged with.
Expand on what they say. If your child says "truck," you say "Yes, a big red truck! The truck is driving fast." This models richer language without correcting them.
Reduce screen time. The Australian Department of Health recommends no screen time for children under 2 and no more than one hour per day for children 2-5. Screens do not build language the way human interaction does.
Sing songs and nursery rhymes. Repetitive songs build vocabulary, rhythm, and memory. Aussie classics like "Kookaburra Sits in the Old Gum Tree" are perfect.
Give them time to respond. After asking a question, wait at least 5 seconds. Toddlers need processing time. Resist the urge to answer for them.
Play, play, play. Play is the language of childhood. Pretend play, in particular, explodes language development — tea parties, dolls, cars, shops, cooking.

How Sonas Woodbridge Supports Speech and Language Development

At Sonas Woodbridge, language development is embedded in everything we do. Our play-based, child-led approach creates a language-rich environment where children are surrounded by meaningful conversation, stories, songs, and responsive educators.

In The Nest, our Nestlings educators narrate routines, sing during nappy changes, and respond to every babble and gesture. This builds the foundation of communication from the earliest days.

In The Family Room, our family grouping model means younger children hear and learn from older children's more advanced language. This natural mentoring accelerates speech development in a way that same-age groupings cannot replicate.

In The Arts Studio and STEM Studio, children are encouraged to describe what they are creating, explain their thinking, and share their ideas with peers. This develops expressive language in authentic, meaningful contexts.

Our educators are trained to recognise when a child may benefit from additional speech and language support, and we work closely with families to connect them with appropriate services. We also collaborate with visiting speech pathologists when families request it.
