There are no toddler-specific 'early signs' to hunt for; instead, watch overall communication — babbling, gesturing, responding to name and emerging words across all settings. A clear speak-at-home-but-never-at-nursery pattern only becomes meaningful nearer the preschool years.","answer_md":"*At 18 to 24 months, a quiet toddler is so often simply a quiet toddler finding her own pace — so what, if anything, should you actually watch at this tender age?*\n\n## In short\nSelective Mutism is a recognised anxiety-based condition where a child speaks comfortably in some settings (usually home) but consistently cannot speak in specific social situations (such as nursery or with unfamiliar adults). Importantly, it is **not usually diagnosed at 18–24 months**, because language is still emerging and shyness with strangers is entirely normal at this stage. There are no \"early signs of Selective Mutism\" to hunt for in a toddler this young — instead, this is an age to observe broad communication and social comfort, and to seek a general developmental check if speech or social engagement seems concerning. Nothing here is a diagnosis.\n\n## Why this label doesn't fit a toddler — and what IS appropriate to watch\nSelective Mutism is typically recognised once a child is in regular settings that *expect* speech — often around 3 to 5 years, when nursery, preschool or new social demands reveal a clear, consistent inability to speak where the child otherwise can. Before that, a child needs to have established expressive language and faced those social situations for the pattern to be meaningful.\n\nAt **18–24 months**, what is healthy and expected includes:\n- **Stranger wariness and shyness** — clinging, going quiet or hiding with new people is normal and protective at this age.\n- **A warming-up period** — many toddlers fall silent in a new place, then relax and chatter once comfortable.\n- **Emerging words** — by around 18 months many toddlers have a handful to 20+ words; by 24 months, often combining two words. There is wide, healthy variation.\n\nRather than looking for mutism, it is more useful to watch for **overall communication and connection**:\n- Does she babble, gesture, point and try to share things with you?\n- Does she respond to her name and to simple requests?\n- Does she use sounds and emerging words to get needs met at home, where she is most comfortable?\n- Does she make warm eye contact and seek you out for comfort and play?\n\n## When a check becomes meaningful\nBook a general developmental check if, by around 18–24 months, your toddler is **not babbling or gesturing**, has **very few or no words**, **does not respond to her name or simple instructions**, or shows little interest in connecting with familiar people — across *all* settings, including home. These are reasons to look at communication broadly, not signs of Selective Mutism specifically. If a clear pattern of speaking freely at home but never at nursery persists into the preschool years, *that* is the time to consider Selective Mutism with a clinician.\n\n## The Pinnacle way\nAt [Pinnacle Blooms Network](/), our first step with a quiet toddler is reassurance and understanding — gently mapping how your child communicates everywhere she goes, not just where she is silent. Where helpful, [speech therapy](https://www.pinnacleblooms.org/top-speech-therapy-center-india-proven-improvement-rate) supports emerging language and confident communication, always at the child's pace. To understand more about this condition as your child grows, see [Selective Mutism](/selective-mutism). 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 steady, strengths-first progress.\n\n## Trusted sources\nAligned with WHO ICD-11 (6B06 Selective mutism), American Academy of Pediatrics and HealthyChildren.org guidance on toddler language milestones and shyness, and ASHA resources on early communication development.\n\n**Next step —** if you'd simply like reassurance about your toddler's communication, book a gentle developmental screen with our clinical team on WhatsApp at +91 91001 81181, and let's understand your child together.\n\nThis is general information, not a diagnosis — individual assessment and diagnosis require an appropriately qualified healthcare professional.","canonical":"https://pinnacleblooms.org/ask/what-are-the-early-signs-of-selective-mutism-in-a-18-to-24-month-old","editorial":{"reviewed_at":"2026-06-11T20:12:18.613642+00:00","reviewed_by":null,"developed_by":"SETU Consortium · Pinnacle Blooms Network"},"alternates":[{"href":"https://pinnacleblooms.org/ask/what-are-the-early-signs-of-selective-mutism-in-a-18-to-24-month-old","lang":"en","indexable":true},{"href":"https://pinnacleblooms.org/ask/what-are-the-early-signs-of-selective-mutism-in-a-18-to-24-month-old-te","lang":"te","indexable":true}],"dimensions":[{"key":"conditions","label":"Conditions"}],"meta_title":"Selective Mutism Signs in 18–24-Month-Olds","meta_robots":"index, follow, max-image-preview:large","everyday_tip":"Give your toddler unhurried warm-up time in new places — stay close, narrate gently, and don't pressure her to perform or 'say hello'.
