Early Indicators of Developmental Language Disorder

A toddler who understands everything but says little, or strings words together late, may be showing the earliest signature of DLD — the pattern a paediatrician is uniquely placed to catch first.

In short

Watch for language that is persistently delayed or atypical relative to age, in a child with otherwise typical hearing, non-verbal cognition and social reciprocity — and where the difficulty is not better explained by another condition. The most actionable early indicators are no babble by 12 months, fewer than 50 words and no word combinations by 24 months, and persistent difficulty understanding or producing language beyond age 3 despite normal hearing.

Early indicators that warrant attention

Expressive markers

• Late or sparse babble; limited consonant variety by 12 months
• Fewer than ~50 words and no two-word combinations by 24 months
• Reduced vocabulary growth, frequent word-finding pauses, over-reliance on gesture or generic terms ("that one", "thing")
• Immature grammar persisting beyond peers — omitted tense/plural markers, simplified sentence structure

Receptive markers

• Difficulty following age-appropriate multi-step instructions despite confirmed normal hearing
• Apparent "not listening" that is actually impaired comprehension

Distinguishing features

• Social reciprocity, eye contact and shared attention are typically intact — this helps separate DLD from autism spectrum presentations
• Non-verbal play and problem-solving are broadly age-appropriate, distinguishing DLD from global developmental delay
• A family history of language or literacy difficulty raises the index of suspicion

When to refer

Confirm hearing first — an audiology check is mandatory before attributing delay to DLD. Persistent concern at or after 24 months, parental report of slow language progress, or a plateau in vocabulary warrants referral to speech and language therapy and, where indicated, multidisciplinary developmental assessment. A child need not meet full ICD-11 criteria for developmental language disorder to benefit from early speech therapy — "watchful waiting" past age 3 without progress is not advisable, as early intervention measurably improves trajectory.
