Supporting Social Development in Your 6-to-9-Month-Old

At six to nine months, your baby is becoming a tiny social explorer — and your warm, everyday responses are the most powerful tool you have.

In short

You support a 6-to-9-month-old's social development through warm, responsive, back-and-forth interaction woven into ordinary moments — smiling and talking face-to-face, playing peek-a-boo, naming what your baby looks at, and following their lead. At this age babies thrive on the rhythm of you do something, I respond, you respond back — these gentle exchanges build the foundations of connection, trust and communication. You do not need special toys or training, just frequent, joyful, tuned-in attention.

How to support social development

• Serve-and-return play — when your baby babbles, coos or reaches, respond as if it's a conversation. Pause, look, smile, and answer back. This turn-taking is the heart of social learning.
• Face-to-face time — hold your baby so they can see your face during feeds, nappy changes and cuddles. Babies this age love studying expressions and copying them.
• Peek-a-boo and simple games — covering your face and reappearing teaches anticipation, shared joy and that people return when they go away.
• Name and narrate — when your baby looks at the fan, the dog or a spoon, name it and share the moment. Following their gaze (joint attention is just beginning) builds connection.
• Respond to their cues — comfort them when upset, mirror their delight, and let them rest or look away when they need a break. Reading and answering cues teaches babies that the social world is safe and reliable.
• Let other gentle faces in — familiar family members talking, singing and playing widens your baby's social world.

Some wariness of strangers and a preference for you around this age is healthy social development, not a problem — it shows your baby is forming strong attachments.

When to seek a check

Every baby's pace differs, but it's worth a friendly developmental check if by around 9 months your baby rarely makes eye contact, doesn't smile back at you, shows little interest in faces or familiar people, doesn't respond to their name or sounds, or doesn't babble or share emotions. A check at this stage is simply reassurance and early support — never a label.
