Social greeting: by what age, and what teachers can expect

A wave, a "hi", a smile back across the classroom — social greeting is one of the warmest signs a child is tuning in to others.

In short

Most children begin responding to social greetings — smiling back, waving, or saying "hi" and "bye" — between around 12 and 18 months, and use them more reliably and on cue by 2 to 3 years. By the time a child starts school (around 3–5 years), a teacher can usually expect a child to return a greeting, respond to their name, and join simple group hellos. Every child arrives on their own timeline, and a little prompting in the early school years is completely typical.

What a teacher can expect in class

Greeting is a social-communication skill (ICF domain d7, interpersonal interactions), and it grows in steps:

• 12–18 months — waves bye-bye, smiles in response to a familiar adult, may say "hi".
• 2–3 years — greets familiar people, often with a verbal or gestural prompt; beginning to greet peers.
• 3–5 years — responds to "good morning", returns a greeting to teacher and classmates, joins a group hello with growing independence.

In class, expect warmth to vary by temperament — some children greet readily, others are slow to warm up and that is normal. Helpful signs are: the child responds when greeted, makes brief eye contact or orients to the speaker, and copies peers' greetings over time. Gentle modelling — greeting the child by name daily — usually does the work.

When to flag

Share a note with parents if a child, past age 3, consistently does not respond to their name or any greeting across several weeks, shows no waving or pointing, or has lost a skill they once had. That is a prompt for a general developmental check, not a cause for alarm.
