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.

*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®](/ask/what-is-the-abilityscore-and-how-is-it-calculated) 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](/emotional) developmental check through [behaviour therapy](/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.

This is general information, not a diagnosis — individual assessment and diagnosis require an appropriately qualified healthcare professional.
