CDC Learn the Signs. Act Early. Milestones
Should my child have a CDC-LTSAE milestone check?
The CDC "Learn the Signs. Act Early." milestones are free, parent-friendly screening checklists — not a clinical assessment. 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.
Free, friendly milestone checklists you can use at home — and a clear next step if anything looks worth a closer look.
In short
The CDC "Learn the Signs. Act Early." 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.What it involves
It's genuinely simple — most parents complete it in minutes:- 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.
- Tick what your child already does. Each item is plain-language, e.g. "smiles to get your attention," "says two words together," "plays pretend."
- 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.
- Use the free CDC Milestone Tracker app if you prefer reminders and a running record over time.
This is a watch-and-share tool to guide a conversation — with your paediatrician or a Pinnacle clinician — not a verdict on your child.
So should your child have one?
Yes — 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.The Pinnacle way

What to watch
Watch for any milestone that hasn't appeared by your child's age band, and especially for a skill your child once had and has now stopped doing — that loss of a skill always warrants a prompt clinical conversation. Trust your instinct too: if something feels off even when the checklist looks fine, ask for a developmental check.

Frequently asked
Is the CDC-LTSAE checklist a diagnosis?
No. It is a free screening tool that flags whether your child may need a closer look — it never diagnoses. Only a qualified clinician can interpret a concern and confirm what it means, through a structured developmental assessment.
At what ages should I use the milestone checklists?
CDC checklists are organised by age band: 2, 4, 6, 9, 12, 15, 18, 24 and 30 months, then 3, 4 and 5 years. Using them at each well-child visit age is a good habit for every family.
What if my child misses a milestone?
One missing item isn't a cause for alarm, but it is worth noting and sharing with a clinician — especially if several are missing, or if your child has lost a skill they once had. Early support works best when it starts early.
How is a Pinnacle AbilityScore different from a CDC checklist?
A CDC checklist is a quick home screen you fill in yourself. An AbilityScore® is a clinician-administered structured assessment at a Pinnacle centre that maps your child against their own baseline and shapes a re-measurable therapy plan.
