# Is my 3-to-6-month-old developing normally in communication?

Between 3 and 6 months, communication shows as cooing, social smiles, babbling, turning to voices and shared eye contact, within a wide healthy range. Celebrate these signs. Seek a developmental check if, by around 6 months, your baby isn't smiling socially, doesn't react to sound or voices, makes very few sounds, or has lost a skill — these are reasons to look closer, not a diagnosis.

*Those first coos, gummy smiles and bright-eyed gazes are your baby's very first conversations — and noticing them means you're already tuned in beautifully.*

## In short
Between 3 and 6 months, communication is mostly about sounds, smiles and shared looks — and there is a wide, healthy range of what's typical. Most babies this age coo and gurgle, smile back at you, turn toward your voice and start to babble. If your little one is doing some of these, exploring their voice and lighting up when you appear, that's a wonderful sign. This is general guidance to celebrate and observe — not a checklist to worry over.

## What to watch at 3–6 months
Communication at this age looks like back-and-forth play long before words arrive. Lovely things to notice and enjoy:

- **Cooing and gurgling** — soft vowel sounds, especially when you chat or play together.
- **Social smiles** — smiling in response to your face and voice, not just on their own.
- **Babbling beginnings** — by around 6 months, sounds like *ba*, *ma*, *ga* may appear.
- **Turning to voices and sounds** — quietening or looking toward a familiar voice.
- **Eye contact and shared joy** — gazing at faces, lighting up when you come close.

Every baby moves at their own pace, so a quiet day here or there is not a concern. A gentle developmental check is worth arranging if, by around 6 months, your baby is **not smiling socially at all, doesn't react to loud sounds or your voice, makes very few sounds, or has lost a skill they once had**. These are simply reasons to look closer — never a diagnosis.

## When to seek a check
If you notice no response to sound (this also warrants a hearing review), no social smiling by 3–4 months, or very little vocal play by 6 months, arrange a calm developmental check now rather than waiting. Your daily observations are valuable — trust them.
