You tick what your child does at their age band across social, language, movement and thinking skills, and flag anything missing. They guide a conversation, never diagnose. If a checklist raises a concern, the next step is a developmental check with a qualified clinician at a Pinnacle Blooms Network centre.","answer_md":"*Free, friendly milestone checklists you can use at home — and a clear next step if anything looks worth a closer look.*\n\n## In short\nThe [CDC \"Learn the Signs. Act Early.\"](/cdc-ltsae) milestone checklists are a free, parent-friendly *screening* tool — not a clinical assessment. They list what most children do at key ages (2 months through 5 years) across social, language, movement and thinking skills, so you can spot early on if your child may need a closer look. They don't diagnose anything; if a checklist raises a flag, the right next step is a proper developmental check with a qualified clinician.\n\n## What it involves\nIt's genuinely simple — most parents complete it in minutes:\n\n- **Pick your child's age band.** CDC milestone checklists are organised by age — 2, 4, 6, 9, 12, 15, 18, 24, 30 months and 3, 4, 5 years.\n- **Tick what your child already does.** Each item is plain-language, e.g. \"smiles to get your attention,\" \"says two words together,\" \"plays pretend.\"\n- **Note anything missing or lost.** A skill that hasn't appeared, or a skill your child once had and has stopped doing, is worth flagging.\n- **Use the free CDC Milestone Tracker app** if you prefer reminders and a running record over time.\n\nThis is a *watch-and-share* tool to guide a conversation — with your paediatrician or a Pinnacle clinician — not a verdict on your child.\n\n## So should your child have one?\nYes — using milestone checklists regularly is a healthy habit for every family, because early support works best when it starts early. But remember the limits: a checklist can flag a concern, yet only a clinician can interpret it in the full context of your child's history, environment and overall development. If the checklist looks reassuring, keep tracking at the next age band. If something feels off — whether the checklist flags it or your instinct does — book a developmental check; you never need a \"high enough\" concern to ask.\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 the care of a qualified clinician — never from an online form or a home checklist.

Backed by 2.5 billion+ data points and 25 million+ therapy sessions across 70+ centres, our team turns that into practical [early-intervention and developmental therapy](/early-intervention) you can use at home.
