# What communication milestones should a doctor 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

Map these to ICF Activity & Participation (d3 Communication) when documenting functional impact, not just symptom count.

## 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](https://www.pinnacleblooms.org/top-speech-therapy-center-india-proven-improvement-rate) assessment.

## The Pinnacle way
Developmental measurement supports care planning; diagnosis requires an appropriately qualified healthcare professional. under qualified clinician care; the [AbilityScore®](/ask/what-is-the-abilityscore-and-how-is-it-calculated) is a clinician-administered structured assessment that gives an objective multi-domain baseline to complement your surveillance and track change once intervention begins.
