YOUR QUESTION. A CLEARER NEXT STEP.
When Do Children Usually Develop Socialization?
Socialization begins at birth and grows most visibly between 12 and 36 months, as toddlers move from shared smiles and peek-a-boo to copying adults, playing alongside others, and beginning to take turns. The range is wide and healthy, and warm everyday back-and-forth is the richest way to nurture it.
In this answer 5 sections
Your toddler's first wave, shared giggle and game of peek-a-boo are not just sweet moments — they are socialization unfolding, right on schedule.
In short
Socialization begins from birth and blossoms most visibly between 12 and 36 months. In the toddler years children start to play near and then with others, share smiles and toys, copy what grown-ups do, and begin simple turn-taking. There is a wide, healthy range — many skills arrive in their own time.
How socialization usually unfolds
Around 12–18 months
- Enjoys games like peek-a-boo and pat-a-cake
- Shows you things and points to share interest
- Looks to you for reassurance in new situations
Around 18–24 months
- Copies others — sweeping, talking on a toy phone
- Plays happily alongside other children (parallel play)
- Shows simple affection and may say "mine"
Around 24–36 months
- Begins to take turns and play simple games together
- Notices when another child is upset
- Enjoys pretend play with others
The science
Socialization is one of the core adaptive domains tracked by tools such as the Vineland Adaptive Behavior Scales. It grows through warm, responsive back-and-forth — the everyday "serve and return" of your attention. Toddlers learn social rules by watching and copying trusted adults, so your everyday interactions are the richest classroom they have.

CONNECT THE ANSWER TO YOUR CHILD’S DAY
Something to notice. Something to discuss.
What to notice
Gentle watch-points by 36 months: very little interest in other children, no shared smiling or pointing to show you things, or no copying of simple actions. These aren't a diagnosis — but they're worth a friendly developmental check.
In everyday life
Play one minute of peek-a-boo or roll-the-ball back and forth each day — naming feelings and taking turns. This 'serve and return' is the simplest way to grow social skills.

Bring your questions to a first visitQuestions families ask
At what age do toddlers start playing with other children?
Most toddlers first play alongside others (parallel play) around 18–24 months, then begin simple turn-taking and shared games closer to 30–36 months. This is a normal sequence — true cooperative play deepens after age 3.
Is it normal for a 2-year-old to not share?
Yes. Sharing and turn-taking are still emerging at age 2, and "mine" is a very typical phase. Gentle modelling and praise help these skills grow over the next year.
When should I be concerned about my toddler's socialization?
If by 36 months your child shows little interest in others, no shared smiling or pointing to show you things, or doesn't copy simple actions, a friendly developmental check is wise. This is observation, not diagnosis — only a clinician can assess properly.
