By 3 to 6 months, watch for a baby who doesn't startle at loud sounds, doesn't turn to a familiar voice, or coos and babbles little. These are reasons for a prompt, painless hearing check — not panic. Early hearing support protects later speech and listening, and clear answers come quickly from a simple screen.

*Hearing is how your baby first reaches for your voice in the dark — so when something feels different, listening closely matters.*

## In short
By 3 to 6 months, most babies turn towards voices, calm to familiar sounds, and start cooing and babbling back. Early signs of possible [hearing impairment](https://pinnacleblooms.org/ask/hearing-impairment) include not startling at loud sounds, not turning to your voice, or going quiet rather than babbling. These are reasons to check — not to panic — and a simple hearing screen gives clear answers quickly.

## Signs worth watching (3–6 months)
**Reacting to sound**
- Doesn't startle, blink or stir at sudden loud noises
- Doesn't seem to settle or brighten to a familiar, soothing voice
- Doesn't begin to turn eyes or head towards where a sound comes from

**Voice and babble**
- Little or no cooing by around 3 months
- Not moving towards varied babble ("ba", "ga", "ma") by 6 months, or babble that fades away
- Seems unusually quiet, or only responds when they can see your face

**Everyday cues**
- Notices you only when they see you, not when you speak from behind
- Doesn't quieten or smile to music or rattles out of sight

## The science, simply
Hearing drives early speech. Babies who hear are already mapping the sounds of your language in these months, which is why a quiet or non-responsive baby deserves a prompt check. Many newborns have a birth hearing screen, but hearing can change — so fresh concerns at 3–6 months always warrant a fresh test. A clear hearing check rules concerns in or out painlessly, and early support protects later speech and listening.

## The Pinnacle way
Developmental measurement supports care planning; diagnosis requires an appropriately qualified healthcare professional., under qualified clinician care — read how the [AbilityScore®](/ask/what-is-the-abilityscore-and-how-is-it-calculated) works as a structured, clinician-administered assessment. If hearing is confirmed as a concern, early [speech therapy](https://www.pinnacleblooms.org/top-speech-therapy-center-india-proven-improvement-rate) and listening support help your baby thrive.
