Selective Mutism cannot begin or be identified at 3 to 6 months. It is an anxiety-based condition affecting a child who can already speak but stays silent in specific settings — recognised typically around ages 3 to 5. At infancy, focus on warm early communication: cooing, social smiles, eye contact and emerging babble. Any worry about hearing or responsiveness deserves a gentle general developmental check, never a Selective Mutism label. Only a Pinnacle clinician can assess.

*If your baby of 3 to 6 months is quiet, coos less than you expected, or only babbles sometimes, it is completely natural to wonder — but Selective Mutism is not something that can begin or be seen at this age.*

## In short
You cannot — and should not — worry about [Selective Mutism](/selective-mutism) in a 3-to-6-month-old. Selective Mutism (ICD-11 6B06) is an anxiety-based condition where a child who *can* speak consistently does not speak in specific social settings (often school) while speaking freely at home. It is only meaningful once a child has spoken language and is moving between social environments — typically recognised around ages 3 to 5, not in infancy. At 3 to 6 months, there is no speech to be "selective" about, so this label simply does not apply. What you can do now is enjoy and gently watch your baby's early communication.

## What is actually appropriate to observe at 3–6 months
This is a season of *pre-speech* communication, and these are the warm, normal signs to look for:

- **Cooing and vowel sounds** — "ooh", "aah", gurgling
- **Social smiling** in response to your face and voice
- **Turning towards sounds** and your voice
- **Eye contact and gaze-sharing** during feeds and cuddles
- **Babbling beginning** to emerge around 4–6 months
- **Different cries** for hunger, tiredness, discomfort

These vary widely from baby to baby. A quiet baby is not a worrying baby — temperament differs, and connection (smiling, watching, settling to your voice) matters more than sound volume right now.

## When a communication check does make sense
Selective Mutism becomes a meaningful question only once your child is speaking and you notice they speak comfortably at home but consistently fall silent in particular settings — usually from around 3 years onward. For your baby now, a general developmental check is the right route if you notice your little one rarely makes eye contact, does not respond to loud sounds, isn't smiling socially by around 3 months, or shows no cooing — these point to hearing or early development, not Selective Mutism.

## 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 a baby this young, we focus on celebrating early communication and, if you have any worry about hearing or responsiveness, a gentle developmental check. Our [speech therapy](https://www.pinnacleblooms.org/top-speech-therapy-center-india-proven-improvement-rate) team supports families across every age, beginning with the playful, responsive moments that build language long before first words.

## Trusted sources
WHO ICD-11 (6B06, Selective Mutism); American Academy of Pediatrics communication milestones (healthychildren.org); CDC developmental milestones for early infancy (cdc.gov).

**Next step —** Rather than worry about a label that does not fit this age, enjoy your baby's coos and smiles. If anything about hearing or responsiveness concerns you, [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.
