Cohesion
What a delay in Cohesion means for your toddler
Cohesion is the warm togetherness in your toddler's play — sharing attention, taking turns and feeling connected. A delay means these social-connection skills are emerging more slowly than expected, not that something is wrong. Between 12 and 36 months these skills grow fast, so a gentle developmental check now is wise, because early playful support works best.
Noticing how your toddler joins with you — sharing a glance, a giggle, a back-and-forth moment — and pausing to wonder about it is loving, attentive parenting.
In short
Cohesion is the warm glue of early togetherness — the way your toddler tunes in to you, shares attention, takes turns and feels connected during play and daily routines. A "delay" in Cohesion does not mean something is wrong with your child; it simply means these social-connection moments are emerging more slowly than expected for their age, and a gentle developmental check is wise now. Between 12 and 36 months these skills bloom quickly, and early, playful support works beautifully.What to watch at 12–36 months
Cohesion grows through thousands of tiny shared moments. Gentle flags worth a clinician's calm eye include:- Shared attention — rarely looking from a toy to your face and back, or not following where you point.
- Back-and-forth — little turn-taking in babble, peek-a-boo, rolling a ball, or copying your actions.
- Seeking connection — seldom bringing things to show you, checking your reaction, or coming for comfort.
- Joining in — finding it hard to settle into simple games or routines alongside you or other children.
Many toddlers vary day to day, especially when tired or unwell. The aim is not worry — it is turning small, everyday observations into early opportunities.
The science
Early togetherness — what the ICF calls support and relationships (e3) — is the foundation on which language, play and learning are built. Shared attention and turn-taking at this age are the strongest, most responsive windows for support, which is exactly why a timely, gentle screen matters.The Pinnacle way
A clinical AbilityScore® and any diagnosis are formed only at a Pinnacle Blooms Network centre, under qualified clinician care — never from an online list. Our clinicians build a warm picture of how your child connects, and you can read more about Cohesion and how our speech therapy team nurtures shared attention and back-and-forth play.Trusted sources

What to watch
Seek a developmental check if your toddler rarely shares a glance from toy to your face, seldom follows pointing, shows little turn-taking in babble or simple games, seldom brings things to show you or checks your reaction, or finds it hard to settle into shared routines. Day-to-day variation is normal, especially when tired or unwell.
Try this at home
Build Cohesion in tiny daily moments — sit face to face, follow what your child looks at, name it, then pause and wait for their turn. Peek-a-boo, rolling a ball back and forth, and copying their sounds all grow shared connection.

Frequently asked
Does a Cohesion delay mean my child has autism?
No. A delay in Cohesion simply means social-connection skills are emerging more slowly than expected — it is not a diagnosis of anything. Many toddlers catch up beautifully with gentle, playful support. A clinician's calm review helps you understand what your individual child needs.
What age does Cohesion usually develop?
Shared attention, turn-taking and seeking connection grow rapidly between 12 and 36 months. They show up in everyday play — sharing a glance, pointing, bringing you a toy, joining simple games. Variation between children, and across tired or unwell days, is completely normal.
What can I do at home to support Cohesion?
Sit face to face, follow what your child is interested in, name it, and pause to invite their turn. Simple back-and-forth games like peek-a-boo, rolling a ball, and copying their sounds all build the warm togetherness of connection.
