{"h1":"Signs of cognitive delay in an 18-to-24-month-old","faq":[{"a":"Many 18-month-olds have only a handful of words, and that can be perfectly typical — words often grow quickly between 18 and 24 months. The bigger picture matters: does your toddler point to show you things, follow simple requests, and try to communicate with sounds and gestures? If words and understanding both seem stalled, a gentle developmental check is wise, and hearing is always checked first.","q":"Is it normal for an 18-month-old not to talk much yet?"},{"a":"At this young age, we don't label specific learning differences — those become meaningful much later, around school age. For 18-to-24-month-olds, clinicians simply observe how thinking, play and curiosity are developing and offer support where helpful. Early observation is about opening opportunities, never about fixing a label.","q":"What is the difference between a cognitive delay and a learning difference?"},{"a":"A skill that quietly disappears is worth a prompt, calm developmental check. It doesn't always mean something serious, but it's always worth a clinician's eye sooner rather than later. Trust what you've noticed and arrange a review.","q":"My toddler lost a skill they used to have — should I worry?"},{"a":"Our clinicians use a structured, clinician-administered assessment — including the AbilityScore® — alongside watching how your child plays, explores and communicates.

These are reasons for an early developmental check — not a diagnosis. Hearing is always checked first, and early support at this age works beautifully.","answer_md":"*Every toddler grows at their own pace — noticing how your little one learns, explores and plays is one of the most loving things a parent can do.*\n\n## In short\nBy 18–24 months, most toddlers are busy little explorers — solving simple problems, pretending, pointing to show you things and learning new words week by week. Possible signs of cognitive delay include not using objects the right way (banging instead of stacking or pretend-play), losing interest in exploring, not following simple one-step requests, not pointing to share, or a noticeable plateau in learning new words and skills. None of this is a diagnosis — it simply means a gentle developmental check now is wise, because support at this age works beautifully.\n\n## What to watch at 18–24 months\nThinking and learning at this age show up most in play and curiosity. Gentle flags that deserve a clinician's calm look include:\n\n- **Play that stays very simple** — not moving toward pretend play (feeding a doll, talking on a toy phone) or not using everyday objects for their purpose.\n- **Little problem-solving** — not figuring out simple cause-and-effect toys, shape sorters, or how to get a toy that's out of reach.\n- **Not following simple requests** — \"give me the ball\" or \"come here\" with a gesture, when hearing seems fine.\n- **Few or no words and not pointing** — by 18 months most toddlers point to show you things and have a handful of words that keep growing.\n- **A plateau or loss of skills** — when learning seems to stall, or a skill your child once had quietly disappears.\n- **Less curiosity and exploration** — not noticing new things, not bringing objects to show you, or seeming uninterested in the world around them.\n\nThe goal is never alarm — it is turning everyday observations into early opportunities.\n\n## When to act\nIf you notice several of these together, or a plateau or loss of skills, arrange a developmental check now rather than waiting and watching alone. Hearing is always checked first, since unclear hearing can look like a learning delay. Your daily observations are valuable clinical information — trust them.\n\n## The Pinnacle way\nA 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 list.
