A steady forward trend matters more than any single date — but no babble by 12 months, no words by 16 months, or any loss of sounds warrants a speech and hearing check.","answer_md":"*Those first coos, babbles and excited squeals are your baby's earliest conversations — and they unfold on a wonderfully predictable timeline.*\n\n## In short\nVocalization develops in clear stages across the first three years: cooing from around 2–3 months, babbling (\"ba-ba\", \"da-da\") by 6–9 months, first true words around 12 months, and a fast-growing vocabulary joining into two-word phrases by 24 months. There is a normal range — but a steady forward trend, with rich babble and gesture, matters more than any single date.\n\n## The science of early sounds\nVocalization is the bridge between hearing and speaking. Babies practise sound before meaning:\n\n- **2–4 months** — cooing, vowel sounds, smiling responses\n- **6–9 months** — canonical babble with repeated consonant-vowel chains, turn-taking \"conversations\"\n- **12 months** — first meaningful words; pointing and gesture to share\n- **18 months** — around 10–20 words, lots of jargon-babble\n- **24 months** — 50+ words, beginning to combine two words\n\nGently worth attention: no babble or gesture by 12 months, no single words by 16 months, or any loss of sounds or words already gained — these warrant a [speech therapy](https://www.pinnacleblooms.org/top-speech-therapy-center-india-proven-improvement-rate) check and a hearing review, not a wait-and-see.\n\n## The Pinnacle way\nEvery child's voice finds its own pace, and a clinical AbilityScore® or any diagnosis is formed only at a Pinnacle Blooms Network centre, under the care of qualified clinicians. We map your child's [vocalization development](/vocalization-development) across listening, sounds and play, then build a warm, family-led plan. Curious how we measure progress? See [how the AbilityScore® is calculated](/ask/what-is-the-abilityscore-and-how-is-it-calculated).\n\n## Trusted sources\nGuided by CDC \"Learn the Signs.
