Selective Mutism cannot be identified at 6 to 9 months — it is an anxiety-related condition recognised only once a child can speak and social speech is expected, usually from around 3 years. At this age a baby isn't yet talking, and going quiet around strangers is healthy, expected behaviour. The gentle focus now is babbling, responding to your voice, and shared eye contact; any general concern about hearing or communication deserves a calm developmental check, never a mutism worry.

*If your baby is happy and babbling at home but goes quiet around others, it's natural to wonder — but at 6 to 9 months, this is far too early for Selective Mutism.*

## In short
Selective Mutism (ICD-11 6B06) is an anxiety-related condition where a child who *can* speak comfortably in some settings — usually home — consistently does not speak in specific social situations, such as nursery or with unfamiliar adults. It is recognised only once a child has developed spoken language and a pattern of social speaking is expected, typically from around 3 years and most often noticed when starting preschool or school. At 6 to 9 months your baby is not yet talking, so Selective Mutism cannot be identified — and a quiet, watchful baby around strangers is entirely normal at this age.

## What is actually appropriate to watch at 6–9 months
Rather than speech, this age is about the building blocks of communication and connection. Lovely, expected things to see include:

- **Babbling** — strings like "ba-ba", "da-da", and experimenting with sounds
- **Responding to your voice** — turning towards you, calming to a familiar tone
- **Eye contact and shared smiles** during play and feeds
- **Reacting to their name** beginning to emerge around 9 months
- **Stranger wariness** — quieting, watching or clinging with new people is healthy and expected

Going quiet or solemn around unfamiliar faces is not mutism — it is a sign your baby knows the difference between you and a stranger, which is exactly as it should be.

## When speaking concerns become meaningful
Worries about *not speaking in certain settings* become clinically meaningful only from around 3 years, once language is established and group settings make social speech expected. Before then, the gentle focus is on overall communication milestones. If at any age your baby shows little babbling, doesn't respond to sound, or you feel hearing or connection isn't developing, a general developmental check is the right, calm step — not a Selective Mutism worry.

## The Pinnacle way
A clinical [AbilityScore®](/ask/what-is-the-abilityscore-and-how-is-it-calculated) and any diagnosis are formed only at a Pinnacle Blooms Network centre, under qualified clinician care — never from an online form or a checklist. For your little one, our focus is reassurance and watching the natural unfolding of communication. If you'd like peace of mind, gentle [speech and language therapy](https://www.pinnacleblooms.org/top-speech-therapy-center-india-proven-improvement-rate) and a developmental review can confirm your baby is on track, and you can read more about [Selective Mutism](/selective-mutism) for the years when it actually applies.

## Trusted sources
WHO ICD-11 (6B06, Selective Mutism); American Academy of Pediatrics communication milestone guidance (healthychildren.org); ASHA guidance on early speech and language development (asha.org).

**Next step —** There's nothing to worry about regarding Selective Mutism at this age, but if you'd like reassurance about your baby's overall communication, [book a developmental check](https://www.pinnacleblooms.org/enroll-autism-speech-aba-therapies-india) with a Pinnacle clinician.

This is general information, not a diagnosis — individual assessment and diagnosis require an appropriately qualified healthcare professional.
