My Child Is Not Talking — When Should I Be Worried?

Child Not Talking: What Every Parent Needs to Know

In my clinic, few concerns come with as much raw parental anxiety as this one.

A mother shows me a video on her phone — her 22-month-old son, playing happily, but silent. No words. No pointing. Just play.

“Everyone says boys are slower,” she tells me. “But something feels wrong.”
Her instinct was correct.

A child not talking at the expected developmental stage is one of the most important early red flags in child development. But — and this is equally important — not all speech delays are the same.

The reason behind a child not talking determines everything:

• Who you should consult
• What tests are required
• What outcomes are possible

Let me walk you through this clearly.

"A child not talking is not always a child who cannot talk. The distinction matters — and only a proper assessment can tell you which it is.”

Normal Speech and Language Milestones

Before assessing a child not talking, we need a baseline.

Here is what research-backed developmental science tells us to expect (WHO Child Development Standards; ASHA, 2022):

By 12 months:

• At least 1–3 meaningful words (mama, dada, baba)
• Responds to name
• Uses pointing or gestures

By 18 months:

• Minimum 10–20 words
• Points to show interest
• Uses words to communicate needs

By 24 months:

• 50+ words
• Combines 2 words ("more milk", "daddy go")
• Strangers understand ~50% of speech

By 36 months:

• 200+ words
• Uses 3-word sentences
• Strangers understand ~75% of speech

By 48 months:

• Tells simple stories
• Asks “why” questions
• Strangers understand ~90% of speech

A child not talking at or near these milestones — especially if multiple milestones are missed — requires prompt evaluation, not watchful waiting.

What to Observe: A Parent Checklist

Language

• Does the child respond to their name?
  (Absent by 12 months = significant red flag)
• Does the child use words intentionally to communicate?
  (Not just repetition or echolalia)
• Is the child not talking but making sounds — or completely silent?
  (No babbling by 12 months is a red flag)
• Does the child understand language even if not talking?
  (Receptive vs expressive language difference is clinically important)

Social Communication

• Does the child make eye contact?
  (Reduced eye contact along with a child not talking is a strong red flag)
• Does the child point to share interest?
  (Joint attention is a key milestone)
• Does the child imitate actions or sounds?
  (Imitation is foundational for language development)
• Does the child engage in back-and-forth play (turn-taking)?

Behaviour

• Is the child not talking but communicating through gestures or by leading you?
• Is there any regression — loss of previously acquired words?
  (This requires immediate evaluation)
• Is the child not talking along with repetitive behaviours (lining up toys, spinning, hand-flapping)?
• Does the child appear uninterested in people?

"Language regression — losing words a child previously had — is never just a phase. It requires urgent assessment."

Possible Reasons a Child Is Not Talking: Who to Consult and Tests Required

1. Speech Delay / Expressive Language Delay

The child understands language, makes eye contact, and communicates through gestures, but speech is delayed.

Consult:
Speech-Language Pathologist (SLP), Audiologist

Tests:
Audiometry (pure-tone and speech), REELS, CELF-P2, MacArthur-Bates CDI

2. Hearing Impairment

A child not talking may not be hearing language clearly.

Consult:
Audiologist, ENT Specialist

Tests:
OAE, ABR/BERA, Pure Tone Audiometry, Tympanometry

3. Autism Spectrum Disorder (ASD)

A child not talking along with social and behavioural differences.

Consult:
Clinical Psychologist, Developmental Paediatrician, SLP

Tests:
ADOS-2, ADI-R, CARS-2, M-CHAT-R/F, Vineland Scales

4. Intellectual Disability (ID)

Delay across multiple developmental areas.

Consult:
Clinical Psychologist, Developmental Paediatrician, Neurologist

Tests:
Bayley Scales (BSID-III), MISIC/WISC-V, Vineland-3

5. Childhood Apraxia of Speech (CAS)

Consult:
Speech-Language Pathologist (CAS specialist)

Tests:
DEMSS, Kaufman Speech Praxis Test

6. Selective Mutism

Consult:
Clinical Psychologist (CBT specialist)

Tests:
CBCL, SCARED, Clinical Interview

7. Neurological Conditions

(Landau-Kleffner Syndrome, Rett Syndrome, etc.)

Consult:
Paediatric Neurologist (urgent if regression is present)

Tests:
EEG, MRI Brain, Genetic Testing

Frequently Asked Questions

Q: My child is 18 months and not talking. Should I wait?
No.

At 18 months, a child should have:

• At least 10 meaningful words
• Pointing to share interest

If these are absent, seek evaluation immediately.

Q: My child understands everything but does not speak. Is that a concern?
Yes, evaluation is still necessary.

Possible reasons include:

• Expressive language delay
• Childhood apraxia
• Early autism

Q: Can excessive screen time cause a child not to talk?
Yes, it can contribute to delays.

However:

• Reducing screen time alone is not enough
• Professional evaluation is still important

Q: My son is 2.5 years old and not talking. Family says boys talk late. Is that true?
No.

Developmental red flags are the same for all children.
A 2.5-year-old not talking requires evaluation.
