YOUR QUESTION. A CLEARER NEXT STEP.
Should I worry that my 15-month-old doesn't wave bye-bye?
Not waving bye-bye at 15 months is usually not worrying on its own — what matters is the wider pattern of gestures like pointing, showing, responding to name and shared smiles. If several of these are missing together, a gentle developmental check is a wise next step. Any diagnosis is formed only at a Pinnacle centre under clinician care.

A wave goodbye is a tiny gesture with a big story behind it — so it's natural to wonder when it's coming.
In short
A single missing skill like waving bye-bye at 15 months is usually not a cause for alarm on its own — many warm, healthy toddlers wave a little later. What matters more is the whole picture of how your child connects: do they share smiles, point at things they want, look back at you, and copy little actions? If those social-communication threads are there, waving often follows soon. If several gestures are missing together, a gentle developmental check is a wise, hopeful next step.
What to look for around 15 months
At this age, waving belongs to a family of early gestures that show your child is sharing their world with you. Alongside waving, look for:
- Pointing to ask for or show you something
- Showing or handing you objects to share interest
- Responding to their name by turning to you
- Copying simple actions like clapping or banging
- Eye contact and back-and-forth smiles during play
If your toddler is doing most of these, a not-yet-wave is very likely just a matter of timing. If you notice several of these gestures are absent, or eye contact and shared attention feel limited, that pattern — rather than any one skill — is what's worth checking.
A simple thing you can try
Gestures grow through warm, repeated, face-to-face moments. Make goodbyes playful and exaggerated — wave big, say "bye-bye!" cheerfully, and gently guide your child's hand for a few days. Toddlers learn gestures by watching and copying the people they love most.
The Pinnacle way
A clinical AbilityScore® and any diagnosis are formed only at a Pinnacle Blooms Network centre, under qualified clinician care — never from a single sign at home. If you'd like reassurance, a friendly developmental check can map your child's social and communication milestones and show you exactly where to support them. Explore why a toddler may not be waving at 15 months and how speech and communication therapy builds early gestures.
Trusted sources
Guidance on early social-communication milestones from the American Academy of Pediatrics' HealthyChildren resource and the US CDC developmental milestone framework informs this overview; both describe gestures like waving and pointing as part of a broader social pattern rather than a single pass-or-fail skill.
Next step — If you'd like clarity, book a developmental check with a Pinnacle clinician and see your child's starting point with confidence.

CONNECT THE ANSWER TO YOUR CHILD’S DAY
Something to notice. Something to discuss.
What to notice
Watch the whole pattern, not one skill: does your child point, show you things, respond to their name, copy simple actions, and share eye contact and smiles? If several of these are missing together, arrange a developmental check.
In everyday life
Make goodbyes playful — wave big, say a cheerful 'bye-bye!', and gently guide your toddler's hand for a few days. Children learn gestures by copying the people they love.
Bring your observations and questions to your child’s professional. Choose activities that suit your child’s comfort, abilities and agreed plan.
Bring your questions to a first visitQuestions families ask
Is not waving bye-bye at 15 months a sign of autism?
Not on its own. Waving can simply arrive a little later in many healthy toddlers. Concern is more reasonable when several early gestures — pointing, showing, responding to name, shared smiles — are missing together. A developmental check can give you clear reassurance.
When do most toddlers start waving?
Many babies wave somewhere between 9 and 15 months, but the range is wide. If your child shares attention in other ways, a later wave is usually just a matter of timing.
What can I do to help my child learn to wave?
Make goodbyes warm and exaggerated, wave clearly while saying 'bye-bye', and gently guide your child's hand. Frequent, playful, face-to-face moments help gestures emerge.
When should I seek a developmental check?
If by 15 months your toddler shows few gestures overall, doesn't point or show you things, rarely responds to their name, or shares little eye contact, a gentle developmental check is a wise step.
