Emotional milestones for your 6-to-9-month-old
By 6-9 months most babies share two-way smiles, laugh, light up for familiar people, read your tone, and begin showing healthy wariness of strangers. These are gentle signposts, not a strict checklist — babies vary. Persistent flatness or little eye contact over weeks is worth a friendly developmental check.
In this answer 5 sections
At six to nine months, your baby is becoming a little emotional conversationalist — reaching back to you with feelings, not just needs.
In short
Between 6 and 9 months, most babies share warm two-way smiles, laugh out loud, show clear delight when they see you, and begin to read your tone of voice and facial expressions. You may also notice the first signs of wariness around strangers — a healthy sign your baby knows you are special. Every baby has their own rhythm, so think of these as a gentle map, not a checklist.
What you may see emerging
- Joy and connection — big smiles, belly laughs, and bright excitement when familiar people come close
- Emotional back-and-forth — your baby mirrors your expressions and responds to a happy or soothing voice
- Comfort-seeking — settling when held, calming to your voice, reaching to be picked up
- Stranger awareness — becoming quieter, watchful or clingy with unfamiliar faces (this often begins now and is completely typical)
- Expressing displeasure — clearly showing when they are upset, bored or want a toy back
The science
The ICF describes emotional functions (b152) as how feelings are produced, expressed and regulated. At this age, emotion grows through thousands of small, responsive moments — your warm reply teaches your baby that feelings are safe and shared. This loop is the foundation of later self-regulation and relationships.
The Pinnacle way
A clinical AbilityScore® and any diagnosis are formed only at a Pinnacle Blooms Network centre, under qualified clinician care — never from an online read. If your baby seems flat, rarely smiles or makes little eye contact across several weeks, a gentle emotional developmental check through behaviour therapy support can reassure or guide you early.
Trusted sources
Aligned with the WHO ICF framework for emotional functions (b152) and CDC developmental milestone guidance for infants.

CONNECT THE ANSWER TO YOUR CHILD’S DAY
Something to notice. Something to discuss.
What to notice
Speak to a clinician if, over several weeks, your baby rarely smiles back, seems consistently flat or hard to comfort, makes little eye contact, or shows no joyful response to familiar people.
In everyday life
Play simple face-to-face games — exaggerate a happy or surprised face, pause, and wait for your baby to respond. These tiny turn-taking moments build emotional connection.
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 stranger anxiety at 8 months normal?
Yes — becoming wary or clingy with unfamiliar faces around this age is a healthy sign that your baby clearly recognises and prefers the people who care for them.
My baby doesn't laugh much yet. Should I worry?
Babies vary widely, and some are simply quieter. If your baby still shares smiles, calms to your voice and connects with you, that's reassuring. If there's little emotional response across several weeks, a friendly developmental check can guide you.
How can I support my baby's emotional growth?
Respond warmly and promptly to their cues, play face-to-face games, name feelings aloud, and offer comfort when they're upset. These everyday moments are exactly what builds emotional development.
