Word knowledge grows on a wide timeline, so single-month variation is normal. A frontline health worker should escalate when a child shows no words by 18 months, no two-word phrases by 24 months, doesn't follow simple instructions, isn't pointing or responding to their name, or has lost words once used. Always include a hearing check, and act on a red flag plus parental concern rather than waiting — early referral gives the best results.

*A frontline worker who notices a child's words aren't growing as expected is already doing the most important job — catching it early, with care.*

## In short
Word knowledge — understanding and using words for everyday things — grows on a broad timeline, so single-month variation is normal. As an ASHA or PHC worker, escalate for a developmental check when a child **shows no words by around 18 months, fewer than 10–15 words by 18 months, no two-word phrases by 24 months, doesn't follow simple instructions, isn't pointing or responding to their name, or has lost words they once had**. These are reasons to refer, not a diagnosis — and early referral gives the best results.

## What to watch
Use these practical age markers during home visits and growth-monitoring days:

- **By 12 months** — no babbling, no gestures (waving, pointing), no response to name.
- **By 18 months** — no single words, or doesn't seem to understand simple words for familiar people and objects.
- **By 24 months** — fewer than around 50 words, no two-word combinations ("more milk"), can't follow a one-step instruction.
- **Any age** — loss of words or skills the child previously had, or a parent who is worried.

Also check hearing history (ear infections, no startle to loud sound) — word knowledge depends on hearing, so a hearing check is part of any escalation.

## When to escalate
Refer to the Medical Officer or nearest developmental/early-intervention service **at the first clear flag — do not adopt wait-and-watch beyond a single short review**. A red flag plus parental concern is enough to act. Document what the child does, not only what they don't, and pass on the parent's own observations — they are valuable clinical information.

## The Pinnacle way
A clinical [AbilityScore®](/ask/what-is-the-abilityscore-and-how-is-it-calculated) and any diagnosis are formed only at a Pinnacle Blooms Network centre, under qualified clinician care — never from a checklist. Our team builds a full picture of a child's [word knowledge](/word-knowledge) and hearing, and our [speech therapy](https://www.pinnacleblooms.org/top-speech-therapy-center-india-proven-improvement-rate) clinicians shape playful, family-led support around it.

## Trusted sources
WHO ICD framework and Nurturing Care developmental guidance; CDC "Learn the Signs, Act Early" milestone checklists (cdc.gov); ASHA guidance on early language development (asha.org).

**Next step —** Trust the flag you've noticed. Refer the family to [book a developmental assessment](https://www.pinnacleblooms.org/enroll-autism-speech-aba-therapies-india) with a Pinnacle clinician for a calm, clear review.
