sound production
When to escalate delayed sound production in a child
A frontline health worker should escalate when a child's sound production is clearly behind — little babbling by 12 months, no clear words by 18 months, fewer than ~50 words by 2 years, or speech strangers can't understand by 3 years. Escalate sooner if hearing seems affected or sounds are lost. This is a referral for assessment, not a diagnosis, and early support works best.
A child who isn't making the sounds you'd expect for their age deserves a calm, timely look — and the frontline worker who notices is exactly where early help begins.
In short
Escalate for a developmental and hearing check when a child's sound production is clearly behind the expected pattern — for example, very few consonant sounds by around 12–15 months, no recognisable words by 18 months, or speech that most family members cannot understand by age 3. Always escalate sooner if you suspect the child cannot hear well, or if speech sounds are slipping backwards. This is a referral for assessment, not a diagnosis — and at this stage early support works best.What to watch and when to escalate
Speech sounds build in a predictable order — cooing, babbling, then first words and clearer speech. Useful flags for a frontline health worker:- By 9–12 months — little or no babbling (no "ba-ba", "da-da"), no response to sounds or name. Check hearing first.
- By 18 months — no clear words, or no attempt to copy sounds.
- By 2 years — fewer than around 50 words, or no two-word joining.
- By 3 years — strangers understand less than half of what the child says.
- Any age — loss of sounds or words once used, or any sign the child does not hear well (no startle to loud noise, doesn't turn to voices).
Route promptly to a hearing test alongside the developmental referral — undetected hearing loss is the most common reversible cause and must be ruled out first.
The science
Sound production (ICF d3, communication) depends on hearing, oral-motor control and a language-rich environment. Because the early brain is highly responsive, a child referred at 18 months gains far more than one referred at 4. Escalation is a low-risk, high-value action: most children turn out fine, and the few who need support get it early.The Pinnacle way

Book a developmental assessment and arrange a hearing check so the child gets a calm, clear review early.
What to watch
Escalate if: little or no babbling by 9–12 months, no clear words by 18 months, fewer than ~50 words or no two-word joining by 2 years, or strangers understanding under half the child's speech by 3 years. Escalate promptly for any loss of sounds/words once used, or any sign of poor hearing — arrange a hearing test alongside the referral.
Try this at home
When referring, note a few examples of the sounds or words the child does and doesn't make, and whether they turn to voices or sounds. These simple observations give the clinician a clear starting picture.

Frequently asked
Should hearing be checked before assuming a speech problem?
Yes. Undetected hearing loss is the most common reversible cause of delayed sound production. Always arrange a hearing test alongside the developmental referral.
Is escalating too early a problem?
No. Escalation simply means a clinician takes a calm look. Most children turn out fine, and the few who need support gain the most from starting early.
What if a child loses sounds they once made?
Any loss of sounds or words once used should be escalated promptly, at any age, for assessment.
