A young baby has no spoken language yet, so there is nothing to worry about. Instead, enjoy healthy early signs like cooing, social smiling and turning to your voice. Only a clinician confirms any concern.","answer_md":"*A baby's first sounds are how she reaches for you — so it's natural to wonder what her quietness might mean. Here is the reassuring truth about this age.*\n\n## In short\nSelective Mutism cannot be identified in a 3-to-6-month-old — it is an anxiety-based condition seen in older children who *can* speak comfortably in some settings (like home) but consistently cannot in others (like nursery or school). A baby of this age has not yet developed spoken language, so there is simply nothing to be \"mute\" about. What matters now is watching her healthy early communication — cooing, smiling, turning to your voice — and these are wonderfully reassuring milestones to enjoy.\n\n## Why this label does not apply yet\nSelective Mutism (ICD-11 6B06) is usually recognised once a child is expected to talk in social settings — most often between **ages 3 and 6**, when nursery or school begins. It describes a child who speaks freely at home but freezes in specific social situations, driven by anxiety, not by an inability to talk.\n\nA 3-to-6-month-old is far too young for any of this to be meaningful. There is no reason for worry about mutism at this stage.\n\n## What IS lovely to notice at 3–6 months\nInstead of signs of a disorder, look for these healthy early communication cues:\n- **Cooing and gurgling** — early vowel-like sounds (\"aah\", \"ooh\")\n- **Smiling back** at familiar faces (social smile)\n- **Turning towards your voice** or a sound\n- **Watching your face** and making eye contact during cuddles and feeds\n- The beginnings of **babbling** by around 6 months (\"ba\", \"ga\")\n\nThese are the building blocks of communication — enjoy responding warmly to each one.\n\n## When a check makes sense\nThere's no need to think about Selective Mutism for years yet. But a **general developmental check** is wise at any age if your baby is not making eye contact, does not respond to sounds or your voice, is not smiling socially by around 3 months, or makes no cooing sounds at all by 4–6 months. These point to hearing or general development — not to mutism — and are easy to look into early.\n\n## The Pinnacle way\nAt [Pinnacle Blooms Network](/), we celebrate your baby's emerging voice and gently track every milestone through play-based, family-centred support.
