Selective Mutism cannot be identified in a 9-to-12-month-old and has no early signs at this age — it is an anxiety-related condition recognised only once a child is speaking, usually after age 3. At 9–12 months, simply enjoy babble, responsiveness and connection; any concern about hearing or babble warrants a general developmental check, not a mutism worry.

*If your baby babbles less than you hoped, it's natural to wonder — but is Selective Mutism really something to look for at this age?*

## In short
Selective Mutism is not something that can be identified in a 9-to-12-month-old, and there are no "early signs" of it at this age. It is an anxiety-related condition where a child who *can* speak consistently does not speak in specific social situations (like nursery or school) while speaking freely elsewhere — and it is only recognised once a child has developed spoken language, usually after age 2–4 years. What matters at 9–12 months is simply that your baby is babbling, responding to sounds and people, and connecting with you. So please be reassured: this is a time to gently watch communication blossom, not to look for mutism.

## What is actually meaningful to observe at 9–12 months
Rather than signs of any specific condition, these are the joyful, everyday communication milestones to enjoy and notice:

**Sounds and babble**
- Babbling with strings of sounds like "bababa", "dadada", "mamama"
- Trying to copy sounds, tones or simple gestures you make

**Connection and response**
- Turning towards your voice or familiar sounds
- Responding to their own name, and to a simple "no"
- Sharing smiles, eye contact and back-and-forth "conversations" of coos and looks

**Gesture and play**
- Waving bye-bye, reaching up to be held, or pointing towards what they want
- Enjoying simple games like peek-a-boo

A baby being quieter on some days, or shy with unfamiliar faces, is completely normal — stranger wariness is itself a healthy developmental milestone around this age.

## When speech-related concerns become meaningful
Selective Mutism becomes possible to consider only once a child is speaking and we can see a *consistent* difference between settings — typically from around 3 years onward, often noticed when a child starts playgroup or school. At 9–12 months, if your baby is not babbling at all, not responding to sounds, not making eye contact, or has lost skills they once had, that is simply a good reason for a general developmental check — not a sign of mutism.

## The Pinnacle way
At [Pinnacle Blooms Network](/), we celebrate communication as it grows, step by step. If you'd ever like reassurance, a [speech therapy](https://www.pinnacleblooms.org/top-speech-therapy-center-india-proven-improvement-rate) team can guide you on nurturing early babble and connection, and [Selective Mutism](/selective-mutism) support is available for older children when it is genuinely relevant. 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; nothing here is a diagnosis. Across 70+ centres in 4 states and 4.95 lakh+ families served, our aim is gentle, strengths-first reassurance and progress.

## Trusted sources
Aligned with WHO ICD-11 (6B06 Selective mutism), the American Academy of Pediatrics and HealthyChildren.org guidance on early communication milestones, and ASHA resources on speech and language development in infants.

**Next step —** for simple reassurance about your baby's babble and connection, book a developmental check with our clinical team on WhatsApp at +91 91001 81181, and let's enjoy your little one's progress together.

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