18-to-24-month-old
Developmental red flags in an 18-to-24-month-old
By 18–24 months most toddlers use several words, point to share, walk confidently and copy everyday actions. Gentle flags worth a developmental check include very few or no words by 18 months, no two-word phrases by 24 months, no pointing, little eye contact or response to name, not walking by 18 months, or loss of a skill once had. These are reasons to assess early — not a diagnosis — because support at this age works best.
By 18–24 months, your toddler is busily exploring, chattering and connecting — noticing how they're growing is one of the most loving things you can do.
In short
Most 18-to-24-month-olds are stringing words together, pointing to share interest, walking confidently and copying everyday actions. The gentle flags worth a developmental check are: fewer than around 6–10 words by 18 months or no two-word phrases by 24 months, no pointing to show you things, little eye contact or response to their name, not walking by 18 months, or loss of a skill once had. None of this is a diagnosis — it simply means a clinician's calm look is wise now, because support at this age works beautifully.What to watch at 18–24 months
Every child grows at their own pace, and a single item on this list rarely means anything worrying on its own. Bring these to a clinician's attention if they persist:- Communication — very few or no words by 18 months; no two-word combinations ("more milk", "daddy go") by 24 months; not following simple instructions.
- Social connection — not pointing to show you something interesting, limited eye contact, not responding to their name, little shared smiling or bringing things to show you.
- Play and gesture — not copying you (sweeping, talking on a toy phone), no pretend play emerging, not waving bye-bye or clapping.
- Movement — not walking by 18 months, frequent falling, or not using both hands well.
- Loss of skills — any words, gestures or social warmth your child once had and has now stopped using. This always deserves prompt review.
The aim is never alarm — it is turning small everyday observations into early opportunities.
When to act
If you notice several of these together, or if your instinct says something has changed, arrange a developmental check now rather than waiting and watching. What you observe every day at home is genuinely valuable to a clinician — trust it.The Pinnacle way

What to watch
Seek a check if your toddler has very few or no words by 18 months, no two-word phrases by 24 months, no pointing to show you things, little eye contact or response to name, isn't walking by 18 months, or has lost any words, gestures or social warmth once had. Several flags together, or a clear change, are reasons to assess early.
Try this at home
Keep a short phone note of your toddler's words, gestures and how they share interest with you over a week — when they point, what they copy, how they respond to their name. This everyday picture is exactly what a clinician finds most useful.

Frequently asked
How many words should an 18-month-old have?
Many 18-month-olds use around 6–10 or more words, though this varies widely. By 24 months, most begin joining two words together, like "more milk". Very few or no words by 18 months is worth a gentle developmental check — not a diagnosis, just a wise early look.
My toddler doesn't point — should I worry?
Pointing to show you something interesting usually emerges before 18 months and is an important social-communication milestone. If your child isn't pointing to share by this age, especially alongside limited eye contact or few words, it's a good reason to arrange a developmental check.
Is it normal for a 2-year-old not to talk much?
Children vary, and some are quieter than others. But by 24 months most use many single words and start combining two. If your toddler has very few words, isn't following simple instructions, or has stopped using words once had, a clinician's calm review is worthwhile now rather than waiting.
