Signs Your Young Child May Need Speech Therapy

← Back to Blog

Every child develops at their own pace, and there's a wide range of what's considered "typical" when it comes to speech and language. As parents, it can be hard to know whether what you're seeing is just a normal variation — or a sign that your child might benefit from some extra support.

The good news is that early intervention is one of the most effective things you can do for a child with a speech or language delay. The earlier concerns are identified, the easier they tend to be to address. If something feels off, trust your instincts — you know your child best.

This guide walks through the common signs that a young child may benefit from seeing a speech pathologist, broken down by age.

Signs in toddlers (12 months – 3 years)

The toddler years are when language explodes — most children move from babbling to single words to short sentences in a remarkably short window. Common signs that a toddler may benefit from speech therapy include:

• Not saying any words by 15–18 months. Most children say their first word around 12 months and have a small vocabulary by 18 months.
• Saying fewer than 50 words by age 2. By their second birthday, most children have at least 50 words and are starting to combine two words together ("more milk", "Daddy go").
• Not combining words by age 2. If your toddler is only ever using single words, this can be a sign of a language delay.
• Speech that's hard to understand — even for close family members.
• Limited use of gestures such as pointing, waving, or showing objects to share interest.
• Not responding to their name consistently, or appearing not to understand simple instructions.
• Frustration when trying to communicate — frequent meltdowns related to not being understood.

Signs in preschoolers (3 – 5 years)

By the time children reach preschool age, language is becoming more complex and speech is becoming clearer. Things to watch for at this stage include:

• Speech that's still difficult for strangers to understand at age 3 or 4. A rough guide: at age 3, strangers should understand around 75% of what your child says; at age 4, almost all of it.
• Difficulty saying certain sounds — particularly if your child is still leaving sounds out, replacing them with easier sounds, or producing them in unusual ways past the expected age.
• Trouble following two-step or three-step instructions.
• Difficulty answering questions like "what", "where", or "why".
• Short or simple sentences compared with peers, or grammar that's still developing well behind their age.
• Stuttering, repetitions, or "blocks" that have persisted for more than 6 months, or that seem to be causing your child distress.
• Difficulty with social communication — taking turns in conversation, joining in with peers, or understanding non-literal language.

Signs in school-age children (5+ years)

Once children start school, communication challenges can show up in new ways — sometimes as academic struggles, sometimes as social or behavioural concerns. Look out for:

• Ongoing difficulty pronouncing certain sounds (commonly "r", "s", "th", or "l").
• Trouble with reading, spelling, or writing that goes beyond what's expected — language and literacy are closely linked.
• Difficulty understanding what they read even when they can decode the words.
• Struggles with telling stories or explaining events in a clear, organised way.
• Word-finding difficulties — frequent "um" and "you know what I mean?", or struggling to come up with the right word.
• Social communication challenges — difficulty making and keeping friends, missing social cues, or trouble with conversation flow.
• Stuttering or fluency concerns that affect confidence or participation at school.

Signs at any age that suggest a speech pathologist can help

• Your child gets frustrated, upset, or shuts down when trying to communicate.
• Other parents, teachers, or family members have raised concerns.
• You feel you're constantly translating for your child.
• Your child is starting to avoid speaking, or has lost confidence around peers.
• Your gut is telling you something isn't quite right.

What happens at a speech pathology assessment?

A speech pathology assessment is generally a relaxed, play-based session. Your speech pathologist will spend time getting to know your child, observing how they communicate, and chatting with you about their development, your concerns, and your family's goals.

From there, you'll get a clear picture of your child's strengths and any areas that might benefit from support — along with practical recommendations. Sometimes the outcome is reassurance that your child is developing well. Sometimes it's a tailored therapy plan. Either way, you'll leave with more clarity and confidence.
