Speech and Language Delay

Early Signs of Speech and Language Delay at 18–24 Months

By 18–24 months most toddlers understand a lot, gain new words steadily, and begin joining two words. Early signs of speech and language delay include very few words, little gesture, not following simple instructions, or losing words once used — reasons for a friendly developmental check, not alarm, since early support works very well at this age.

Speech & Language Delay: Signs at 18–24 Months — Ask Pinnacle, the Child Development Kośa

Between 18 and 24 months, words usually start arriving in a rush — so when they don't, many parents quietly wonder if they should wait or act.

In short

By 18–24 months most toddlers understand far more than they say, are picking up new words steadily, and are beginning to join two words together. Gentle early signs of a speech and language delay include very few spoken words, little gesture, not following simple instructions, or seeming not to understand everyday talk. These are reasons for a friendly developmental check — not alarm — because early support works beautifully at this age.

Signs worth watching

Understanding (receptive language)
  • Doesn't follow simple one-step instructions like "give me the ball" by around 18 months
  • Rarely points to familiar things when named ("Where's the doggy?")
  • Seems not to respond to their name or to everyday words

Talking (expressive language)

  • Fewer than around 10–20 words by 18 months, or fewer than 50 by 24 months
  • Not combining two words ("more milk", "daddy gone") by 24 months
  • Loses words or babble they once used — this always deserves a prompt check

Social communication

  • Little use of gestures — waving, pointing, showing
  • Limited back-and-forth babble or eye contact during play

A simple first step alongside this is a hearing check, since glue ear and hearing dips are a common, very treatable cause.

The science, briefly

The 18–24 month window is when toddlers typically move from single words into a fast vocabulary "burst" and early word combinations. WHO ICD-11 groups these patterns under 6A01 (developmental speech or language disorders). A delay does not predict a child's intelligence or future — many late talkers catch up, and those who need support respond best when it begins early.

The Pinnacle way

A clinical AbilityScore® and any diagnosis are formed only at a Pinnacle Blooms Network centre, under the care of a qualified clinician — never from an online list. Our team uses a warm, structured assessment to map your child's communication strengths and next steps, then shapes a plan through speech therapy built around play. You can read more about speech and language delay and what helps.

Trusted sources

Aligned with WHO ICD-11 (6A01), the CDC's "Learn the Signs. Act Early." milestones, the Indian Academy of Pediatrics, the American Academy of Pediatrics, and RBSK developmental screening guidance.

What to watch

Seek a prompt check if your toddler loses words or babble they once had, isn't combining two words by 24 months, or doesn't respond to their name — and ask for a hearing test, as ear problems are a common, treatable cause.

Try this at home

Narrate your day in short, clear words and pause to give your toddler a turn — name what they look at, repeat their attempts back slightly expanded ("ball" → "big ball"), and read picture books daily.

Frequently asked

How many words should an 18-month-old say?

Many 18-month-olds say around 10–20 words, but the range is wide. More important than an exact count is steady progress — adding new words over time, understanding everyday requests, and using gestures like pointing and waving.

My toddler understands everything but barely talks — is that a problem?

Strong understanding is reassuring, and some children are simply late talkers who catch up. Still, if your child says very few words or isn't combining two words by 24 months, a gentle developmental check is worthwhile so you have clarity and early support if needed.

Could a hearing problem cause speech delay?

Yes. Even mild or fluctuating hearing loss, often from glue ear, can slow speech and language. A hearing check is a sensible first step alongside any developmental assessment, as it is common and very treatable.

Is it too early to start speech therapy at 18 months?

Not at all. Early, play-based support is highly effective at this age and often involves coaching parents in everyday talk and play, building on your child's natural strengths.
