Seek a developmental check when your child is clearly behind peers across several areas, has stopped progressing, or has lost a skill once mastered. This is a reason to assess early, not a diagnosis, because early support works best.","answer_md":"*Watching your child puzzle things out, remember, and ask \"why\" is one of parenting's quiet joys — and noticing when something feels off is wise, loving attention.*\n\n## In short\nCognitive development — how your child thinks, learns, remembers, solves problems and pays attention — unfolds at its own pace, and a wide range is completely normal. The time to seek a gentle developmental check is when your child is **clearly behind same-age peers across several milestones, has stopped making progress or lost a skill they once had, or struggles in ways that get in the way of play and everyday learning.** This is never a diagnosis — it simply means a calm, early look is wise, because early support works beautifully.\n\n## What to watch, by stage\nCognitive growth shows up in everyday play — exploring, imitating, remembering where toys are, pretending, following simple steps. Gentle flags that deserve a clinician's eye include:\n\n- **By 12 months** — not searching for a hidden toy, not exploring objects (banging, mouthing, dropping), no response to their own name.\n- **By 18–24 months** — not pointing to show interest, no pretend play (feeding a doll, talking on a toy phone), not following a simple instruction.\n- **By 3 years** — difficulty with simple problem-solving, sorting or matching; not understanding \"in/on/under\"; struggling to follow two-step directions.\n- **By 4–5 years** — trouble remembering routines, naming colours or counting a few objects, or staying with a task long enough to finish simple play.\n- **At any age** — **losing a skill** once mastered, or a clear, persistent gap from same-age children across several areas at once.\n\nMany single delays catch up on their own. It is the **pattern** — several areas, no forward progress, or a loss of skills — that tells us a clinician's eye is worth seeking now rather than later.\n\n## When to act\nTrust your instinct. If you see a cluster of these signs, a plateau, or a loss of skills, arrange a developmental check now — waiting rarely helps, and an early, calm review often brings the most reassuring news of all. What you observe every day is valuable information for a clinician.\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.
