YOUR QUESTION. A CLEARER NEXT STEP.
Signs of social delay in an 18-to-24-month-old
At 18–24 months, social development shows as sharing smiles, pointing to show you things, responding to their name, and copying you in play. Gentle signs worth a developmental check include little eye contact or shared joy, not pointing, not responding to name, little interest in others, or not imitating — especially if these appear together or a skill has faded. These are reasons to assess early, not a diagnosis, and hearing should be checked first.
In this answer 5 sections
By 18–24 months, the way your toddler shares smiles, points and copies you tells us so much — and noticing quietly is loving, attentive parenting.
In short
At 18–24 months, social development shows up as your toddler sharing joy with you, pointing to show you things, copying simple actions, and seeking comfort and connection. Gentle signs worth a clinician's eye include little eye contact or shared smiling, not pointing to show interest, not responding to their name, little interest in other people, or not copying you in play. None of this is a diagnosis — it simply means a calm developmental check is wise now, because support at this age works beautifully.
What to watch at 18–24 months
Most toddlers this age are busy connecting — looking back to check you're watching, bringing you toys, and lighting up at familiar faces. Gentle flags that deserve a clinician's eye include:
- Little shared attention — rarely pointing to show you something interesting, or not following your point or gaze.
- Limited eye contact and shared smiles — not often looking to your face to share a feeling or check in.
- Not responding to their name — when said warmly and clearly, with hearing already checked.
- Little interest in others — seeming content alone, rarely watching or copying other children or you.
- Not imitating — not copying simple actions like clapping, waving, or pretend play (feeding a doll, talking on a toy phone).
- Loss of a skill — any social warmth, words or gestures your child once had and seems to have faded.
The goal isn't worry — it's that an early, gentle look turns small questions into early opportunities.
When to act
If several of these appear together, persist, or come with delays in talking or play — or if your child has lost a skill — arrange a developmental check now rather than waiting. First, ask your doctor to confirm hearing, as it underpins social and language growth. Trust your parent instinct: what you see every day is valuable clinical information.

CONNECT THE ANSWER TO YOUR CHILD’S DAY
Something to notice. Something to discuss.
What to notice
Seek a check if your toddler rarely points to show you things, has little eye contact or shared smiling, doesn't respond to their name (with hearing checked), shows little interest in others, doesn't copy simple actions or pretend play, or has lost a social skill once had — especially if several appear together or alongside delays in talking.
In everyday life
During play, pause and wait — hold up a toy, then look to your child's face. Notice whether they point, look back to share, or copy you. A short phone note of these moments gives a clinician a clear, useful picture.
Bring your observations and questions to your child’s professional. Choose activities that suit your child’s comfort, abilities and agreed plan.
Bring your questions to a first visitQuestions families ask
Is it normal for my 18-month-old to play alone a lot?
Some solo play is completely typical at this age — toddlers explore independently. What we look for is whether your child still looks to you to share moments, brings you toys, and lights up at familiar faces. If they rarely connect or check in with you, a gentle developmental check is wise.
My toddler doesn't point yet — should I worry?
Pointing to show you interesting things usually emerges around 14–18 months and is an important social milestone. If your child isn't pointing by 18–24 months, isn't following your point, and shows little shared attention, it's worth a calm developmental review — not a diagnosis, just a useful look.
Could a hearing problem look like social delay?
Yes. Hearing underpins responding to name, social connection and language. Before reading too much into social signs, ask your doctor to confirm your child's hearing, as undetected hearing differences can affect how a toddler engages with people.
What should I do if I notice several of these signs?
Trust your instinct and arrange a developmental check now rather than waiting. Support works beautifully at this age. A Pinnacle clinician will build a full picture of your child's strengths and shape support around joyful play — early steps are gentle, not alarming.
