cohesion
What it means if your toddler cannot link ideas (cohesion) yet
Between 12 and 36 months, cohesion — how a child links words, ideas and play steps together — is still developing, and wide variation is normal. Not yet joining words or connecting play usually means more time and rich back-and-forth play is needed, not that something is wrong. A gentle developmental check is wise if the gap is widening or comes with few words, little response to name or loss of a skill. This is reassurance and early opportunity, never a diagnosis.
Watching how your toddler links their ideas, words and play together is one of the gentlest, most loving things a parent can notice.
In short
"Cohesion" simply means how a child holds ideas together — joining words into little phrases, linking one play step to the next, or staying on a shared topic for a few turns. Between 12 and 36 months this skill is still blooming, and lots of variation is completely typical. If your child is not yet stringing thoughts or words together, it usually means they need a little more time and rich back-and-forth play — not that anything is wrong. A calm developmental check is wise only when the gap is widening or travels with other delays.What to watch between 12–36 months
Cohesion grows on top of attention, language and play, so it appears gradually. Gentle flags that deserve a clinician's friendly look include:- By around 18–24 months — not yet joining two words ("more milk", "daddy go") or not linking simple play steps (feed the doll, then put her to bed).
- By 24–36 months — speech that stays in single words, or play and talk that jump about without connecting from one moment to the next.
- Travelling with other differences — few words overall, little response to name, limited eye contact or shared smiling, or not pointing to show you things.
- Loss of a skill your child once had.
The aim is never alarm — most toddlers simply need more time and more playful conversation. Early observation turns small questions into early opportunities.

What to watch
Seek a friendly check if, by 18–24 months, your child isn't joining two words or linking simple play steps; if by 24–36 months speech stays in single words or play jumps about without connecting; or if there are few words overall, little response to name, limited eye contact, no pointing, or loss of a skill once had.
Try this at home
Narrate your day in linked little steps — "First we wash hands, then we eat" — and pause for your child to add the next idea. These small back-and-forth moments are exactly how cohesion grows.

Frequently asked
Is it normal that my 2-year-old isn't linking words yet?
Often, yes. Many toddlers are still single-word speakers around two and begin joining words and ideas over the following months. If your child isn't combining two words by around 24 months, a gentle developmental check can offer reassurance and early support.
What is cohesion in a toddler's development?
Cohesion is how a child holds ideas together — joining words into phrases, linking one play step to the next, and staying on a shared topic for a few turns. It builds on attention, language and play, so it appears gradually through the toddler years.
Will my child catch up on their own?
Many children do, especially with plenty of rich back-and-forth conversation and play. A clinician's calm look helps you know whether to simply keep nurturing it or to add a little extra support — early help works beautifully at this age.
