Early Signs of Social Communication Difficulties at 18–24 Months

Every toddler babbles, points and plays at their own pace — so how do you know when gentle, joyful connection isn't quite coming together yet?

In short

At 18–24 months, early signs of social communication difficulties show as a pattern of reduced back-and-forth connection: limited eye contact or shared smiles, little pointing or showing things to share interest, few gestures like waving or clapping, slow or absent first words, and not responding to their own name. One quiet day is nothing — what matters is a consistent pattern across weeks. These are signs to observe and discuss together, never to diagnose at home.

Early signs to watch (18–24 months)

Connecting and sharing attention

• Rarely makes warm eye contact or shares a smile back and forth with you
• Doesn't often point to show you something interesting ("look, a dog!") just to share, not only to request
• Seldom brings or shows you toys to share the moment
• Doesn't reliably follow your point or look where you're looking

Responding to others

• Doesn't turn or respond when you call their name (after hearing is checked)
• Limited response to simple words, smiles or playful sounds from you

Gestures and early words

• Few gestures by 18 months — little waving "bye", clapping or reaching up to be lifted
• Very few or no clear words by 18–24 months, or words that appeared then faded
• Little copying of your sounds, actions or simple play

Play and togetherness

• More interest in objects than in people much of the time
• Little pretend play (feeding a doll, pretend phone) beginning to emerge

What matters is the overall pattern across several areas, not a single milestone. Toddlers vary widely, and a hearing check is an important first step whenever words are slow.

When to seek a check

Book a developmental check if, by around 18–24 months, you notice several of these together — especially limited pointing, gestures, name-response or shared attention — or if you feel your child's words or social connection have stalled or slipped. Early support at this age is wonderfully effective, because a toddler's brain is busy building exactly these connection skills right now.

The Pinnacle way

At Pinnacle Blooms Network, we start by understanding how your child already connects — through play, sound and shared joy — and build from those strengths. Support such as speech therapy and our work on social communication difficulties nurtures pointing, gestures, turn-taking and early words in everyday, playful ways. A clinical AbilityScore® and any diagnosis are formed only at a Pinnacle Blooms Network centre under qualified clinician care; nothing here is a diagnosis. Across 70+ centres in 4 states and 4.95 lakh+ families served, our aim is steady, strengths-first progress.

Trusted sources

Aligned with WHO ICD-11 guidance, the developmental milestone resources of the CDC and HealthyChildren.org (American Academy of Pediatrics), and ASHA guidance on early social communication and language development in toddlers.
