Social interaction develops across the toddler years (12–36 months), not on a single birthday: social smiling by ~2 months, pointing and back-and-forth gestures by 12 months, pretend play and imitation by 18–24 months, and shared play with other children by 2–3 years. These are guides, not deadlines.

*Your baby's first shared smile, the giggle that asks for one more round of peek-a-boo — these are the earliest threads of social connection, and they begin far sooner than most parents expect.*

## In short
Social interaction unfolds across the whole toddler period (12–36 months), not on a single birthday. Expect social smiling by around 2 months, back-and-forth gestures and pointing to share interest by 12 months, simple pretend play and copying others through 18–24 months, and growing interest in playing near and then with other children by 2–3 years. These are guides, not deadlines — children vary.

## How social skills grow
- **By 12 months** — responds to their name, looks where you point, waves and reaches up to be picked up, enjoys turn-taking games.
- **By 18 months** — points to show you something interesting, brings toys to share, copies your actions, looks to your face for reassurance.
- **By 24 months** — simple pretend play (feeding a doll), excitement around other children, imitates words and gestures.
- **By 36 months** — takes turns, shows concern when a friend cries, joins in cooperative play.

## The science
Social interaction develops through serve-and-return — each smile, sound or gesture your child offers, and your warm response, wires the brain for connection. It is one of the clearest early windows on development, which is why it is gently checked at routine reviews. Persistent absence of name-response, pointing, or shared joy across settings is worth a developmental check rather than "wait and see".
