Communication
Communication milestones to check at routine visits
At routine visits, check communication against age-anchored milestones — social signals and babble by 9–12 months, first words by 12–16 months, two-word combinations by 24 months, sentences by 36 months. Refer on no babble/gesture by 12 months, no words by 16 months, no two-word phrases by 24 months, or any loss of skills, with parallel audiology referral.
Every well-child visit is a window — and communication is one of the most sensitive signals of how a child's development is unfolding.
In short
At routine visits, track communication against age-anchored expectations: pre-verbal social signals first, then babble and gesture, single words, word combinations, and finally connected, intelligible speech. Surveillance at every contact plus structured screening at the standard intervals catches delay early. Persistence across settings, plateau, or any loss of skills — not a single missed milestone — is what should prompt referral.Milestones to check, by age band
By 9 months- Reciprocal smiling and shared affect; responds to voice and turns to sound
- Canonical babble ("ba-ba", "da-da"), takes turns in vocal exchanges
- Follows a gaze; early joint attention emerging
By 12 months
- Responds to name; uses gestures — points, shows, waves
- Babble with varied consonants; first words may appear
- Understands simple words and "no"
By 18 months
- Several single words used meaningfully; points to share interest
- Follows a one-step instruction without gesture
- Imitates words and actions
By 24 months
- Two-word combinations ("more milk"); ~50-word expressive vocabulary
- Speech ~50% intelligible to familiar listeners
- Follows two-step related instructions
By 36 months
- Short sentences; speech largely intelligible to strangers
- Answers "what" and "where"; uses pronouns and plurals
- Conversational turn-taking sustained

When to refer
Apply clear stop-rules at any visit: no babble or gesture by 12 months, no single words by 16 months, no two-word phrases by 24 months, or any loss of previously acquired speech or social communication at any age. Refer in parallel for an audiology check — undetected hearing loss is the single most important reversible cause. Persistent parental concern is itself a sensitive indicator and justifies onward speech therapy assessment.The Pinnacle way

What to watch
Escalate to same-week referral on any regression (loss of words, babble or social engagement) at any age, or when communication delay coexists with hearing concern, feeding difficulty or motor red flags — these warrant action rather than watchful waiting.
Try this at home
High-yield consult check: response to name, pointing to share interest, and number of meaningful words for age. Any two weak with parental concern is enough to refer — and always check hearing in parallel.

Frequently asked
At what age is no single word concerning?
Absence of any meaningful single word by 16 months is a stop-rule warranting referral, alongside no babble or gesture by 12 months and no two-word phrases by 24 months. A single missed milestone in an otherwise thriving child may reflect normal variation, but persistence across settings or any loss of skills should always prompt assessment.
Should I refer for speech delay before checking hearing?
Refer in parallel. Undetected hearing loss is the most important reversible cause of communication delay, so an audiology check should accompany — not delay — onward developmental assessment whenever speech or language is behind expectations.
How does the AbilityScore® help in a referred child?
It is a clinician-administered structured assessment that provides an objective, multi-domain baseline to complement your surveillance and track change once intervention begins. It supports clinical judgment and is not a diagnostic test; diagnosis remains a clinical decision made at a Pinnacle Blooms Network centre.
