Social milestones for a 9-to-12-month-old
Between 9 and 12 months most babies respond to their name, play back-and-forth games like peek-a-boo, wave bye-bye, point to share interest, and look to your face for cues. Milestones are a guide, not a deadline. A friendly check is worth it if there's no babble, no gesture, no response to name by 12 months, or any loss of skills.
In this answer 5 sections
Around the first birthday, your baby is becoming a little social being — pointing, waving, and watching your face for cues. These are some of the most delightful months to witness.
In short
Between 9 and 12 months, most babies become warmly social — they respond to their name, play simple back-and-forth games like peek-a-boo, wave bye-bye, point or reach to share interest, and look to your face to gauge how to feel about new things. These are typical patterns, not a checklist your baby must complete on an exact day. Babies grow at their own pace, and a wide range is perfectly normal.
Social milestones to enjoy and watch for
Connecting with you
- Turns and responds when you say their name
- Looks for you when you leave the room and lights up when you return
- Holds out arms to be picked up
- May show shyness or clinginess around unfamiliar people — a healthy sign of attachment
Sharing and communicating
- Plays back-and-forth games — peek-a-boo, pat-a-cake, give-and-take with toys
- Points, reaches or gestures to show you something interesting ("joint attention")
- Waves bye-bye and may copy simple actions like clapping
- Babbles with changing tones, almost like a little conversation
Reading your cues
- Glances at your face to see how you react before trying something new
- Enjoys looking at faces and may offer a toy to share
A gentle word on timing
Milestones are a guide, not a deadline. Some babies wave early; others point first. What matters most is steady forward progress and rich back-and-forth connection with you. If by 12 months you notice no babbling, no gestures (no pointing, waving or reaching to show), no response to their name, or a loss of skills your baby once had, it's worth a friendly developmental check — and a quick hearing review — rather than waiting.
The Pinnacle way
A clinical AbilityScore® and any diagnosis are formed only at a Pinnacle Blooms Network centre, under the care of a qualified clinician — never from an online list. If you'd simply like reassurance or have a question, a developmental screen is a calm, supportive first step, and our speech and communication support can help nurture early gestures and babble.

Aligned with CDC "Learn the Signs. Act Early." milestone guidance, the American Academy of Pediatrics and its HealthyChildren.org parent resources, and WHO nurturing-care guidance on early childhood development.

Something to notice. Something to discuss.
What to notice
By 12 months, a friendly developmental check is worth arranging if you notice no babbling, no gestures (no pointing, waving or reaching to show), no response to name, or any loss of skills your baby once had.
In everyday life
Play simple turn-taking games every day — peek-a-boo, rolling a ball back and forth, or pausing in pat-a-cake so your baby fills in the next move. These small exchanges build social back-and-forth.
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
My 11-month-old isn't waving yet — should I worry?
Not necessarily. Waving often appears between 9 and 12 months, but the range is wide and some babies show other gestures first, like pointing or reaching to share. What matters is steady progress and warm back-and-forth with you. If by 12 months there are no gestures at all, no babble and no response to name, a friendly developmental check is a calm next step.
Is being shy or clingy around strangers a problem at this age?
It's usually a healthy sign. Stranger awareness and clinginess around 9 to 12 months reflect your baby's growing attachment to familiar caregivers. It typically eases with time and gentle, reassuring exposure to new people.
When does it make sense to ask a professional?
Trust your instinct. If you feel something is different, or by 12 months your baby shows no babbling, no gestures, no response to their name, or has lost skills they once had, arrange a developmental check and a hearing review rather than waiting. Early support, when needed, is gentle and effective.
