YOUR QUESTION. A CLEARER NEXT STEP.
At what age should a child use social greetings?
Children typically begin simple social greetings — waving, smiling back, saying "hi" — between 9 and 15 months, and greet familiar people warmly by 2 to 3 years. Some variation is normal; steady progress in connecting with people matters most.
In this answer 6 sections
The first wave, the first "hi" — a social greeting is one of the warmest signs that your child is reaching out to their world.
In short
Most children begin to share simple social greetings — waving "bye-bye", returning a smile, or saying "hi" — between 9 and 15 months, and by 2 to 3 years they greet familiar people warmly and on cue. Every child grows at their own pace, so a little earlier or later is usually perfectly typical. What matters is steady, joyful progress in connecting with people.
How social greeting unfolds
A social greeting is an early building block of social communication (ICF chapter d7, interpersonal interactions). It blends attention to people, imitation, and intent to connect. A simple roadmap:
- 9–12 months — waves in imitation, enjoys peek-a-boo, brightens at a familiar face
- 12–18 months — waves "bye" with meaning, may say "hi"
- 2 years — greets familiar adults with a word or gesture, with reminders
- 3 years — initiates simple greetings more independently and warmly
The science
Greetings emerge from joint attention and social motivation — the same shared back-and-forth that underpins later conversation. They are best learned through everyday warmth, not drilling: babies copy the people who light up for them.
When to check in
If, by around 18 months, your child rarely responds to their name, shares few smiles, or uses little gesture or eye contact, a gentle developmental check is worthwhile — not a cause for alarm, just a sensible next step.

Something to notice. Something to discuss.
What to notice
By around 18 months, watch for rarely responding to name, few shared smiles, or little gesture and eye contact — a gentle developmental check is then worthwhile.
In everyday life
Model greetings yourself with delight — wave and say "hi" and "bye-bye" warmly at doorways, video calls and visitors, then pause and give your child a moment to copy you.

Bring your questions to a first visitQuestions families ask
When do babies start waving bye-bye?
Many babies wave "bye-bye" in imitation between 9 and 12 months, and use it with meaning by around 12 to 15 months. A little later is still within the typical range.
My 2-year-old won't greet people — is that a problem?
Many 2-year-olds greet only with reminders or feel shy with strangers, which is normal. If your child also rarely responds to their name or shares few smiles, a gentle developmental check is sensible.
How can I encourage my child to greet people?
Model greetings warmly yourself, keep them playful, and praise any attempt. Peek-a-boo, songs with waving, and greeting toys all build the joyful back-and-forth behind real greetings.
