Diagnosis, where needed, requires an appropriately qualified healthcare professional.","answer_md":"*When you're tracking your little one's growth, two words crop up again and again — and knowing the difference can turn worry into clear, calm action.*\n\n## In short\nA **milestone delay** means your child is reaching a skill — like sitting, talking or walking — later than the typical age range, but often catching up with time or a little support. A **developmental red flag** is a specific sign that suggests development may need a closer look sooner rather than later, such as losing a skill once gained or not responding to sound. Put simply: a delay is *slower progress*, while a red flag is a *signal to check now*. Either way, an early developmental check brings clarity — and most children do beautifully with timely, playful support.\n\n## Understanding the difference\n- **Milestone delay** — A milestone is a skill most children show by a certain age (rolling, babbling, first words, walking). A *delay* means your child hasn't reached it within the usual window. Many children simply take their own time and catch up, especially with encouragement and play.\n- **Developmental red flag** — These are particular signs that warrant a prompt check, whatever the age. Examples include: not turning to sounds or voices, no babbling or gestures (like pointing or waving) by around a year, loss of words or skills a child once had, no eye contact or social smiling, or one side of the body moving very differently from the other.\n- **Why it matters** — A single late milestone is common and often nothing to worry about. But a red flag, or several delays together, is the developmental world's way of saying *let's look closer, gently and early* — because early support consistently helps most.\n\n## When to seek a check\nBook a developmental review if your child shows any red-flag sign, misses several milestones across areas (movement, speech, social, play), or **loses a skill** they previously had. Trust your instinct too — if something feels different, a check brings reassurance or an early start, both of which are wins for your child.\n\n## The Pinnacle way\nAbilityScore® is part of Pinnacle’s developmental assessment.
