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.","answer_md":"*Hearing is how your baby first reaches for your voice in the dark — so when something feels different, listening closely matters.*\n\n## In short\nBy 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.\n\n## Signs worth watching (3–6 months)\n**Reacting to sound**\n- Doesn't startle, blink or stir at sudden loud noises\n- Doesn't seem to settle or brighten to a familiar, soothing voice\n- Doesn't begin to turn eyes or head towards where a sound comes from\n\n**Voice and babble**\n- Little or no cooing by around 3 months\n- Not moving towards varied babble (\"ba\", \"ga\", \"ma\") by 6 months, or babble that fades away\n- Seems unusually quiet, or only responds when they can see your face\n\n**Everyday cues**\n- Notices you only when they see you, not when you speak from behind\n- Doesn't quieten or smile to music or rattles out of sight\n\n## The science, simply\nHearing 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.\n\n## The Pinnacle way\nDevelopmental 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.
