At 12–18 months, Social Communication Difficulties is not formally diagnosed, but this is a key window to gently observe how your toddler connects — name response, eye contact, pointing, gestures and babble. A persistent pattern of several missed social-communication behaviours, or loss of skills once present, deserves a friendly developmental check rather than waiting. Only a Pinnacle clinician can assess; never an online form.

*If your little one isn't pointing, babbling back, or lighting up when you call their name, it's natural to wonder what's typical at this age — and you're right to ask.*

## In short
At 12–18 months, the goal isn't to spot a label but to notice whether your toddler is *connecting and communicating* in the everyday back-and-forth ways babies do. [Social Communication Difficulties](/social-communication-difficulties) (ICD-11 6A01.22) is not formally diagnosed at this young age — but this is exactly the window where gentle observation matters most, because early support is so effective. What you're watching for are persistent gaps in eye contact, shared attention, gestures and early sounds — not a single missed milestone.

## What to gently watch for at 12–18 months
Most toddlers this age are busy little communicators. It's worth a friendly developmental check if, over several weeks, you notice your child rarely:

- **Responds to their name** or turns to your voice
- **Makes warm eye contact** during play, feeding or cuddles
- **Points or shows** things to share interest ("look at that!")
- **Uses gestures** like waving bye-bye, reaching up, or shaking head
- **Babbles back** in to-and-fro "conversation", or has lost words/sounds they once used
- **Shares smiles and joy** with you, or follows where you point

A single item on an off day means little — toddlers vary enormously. What deserves a closer look is a *pattern* of several of these, especially the loss of any skill your child previously had. That last one — losing words, babble or social warmth — is always worth a prompt conversation with a clinician.

## When this becomes a concern
Think of 12–18 months as a *watch-and-support* stage, not a diagnosis stage. The kindest, most useful step is a general developmental check rather than waiting to see. Early communication and play-based support given now works with your child's fast-growing brain — there is real power in starting early, and nothing is lost by checking.

## The Pinnacle way
