Early Signs of Social Communication Difficulties at 3–6 Months

At three to six months, your baby is just beginning the beautiful conversation of glances, gurgles and smiles — and it's natural to wonder whether those exchanges are unfolding as they should.

In short

At 3–6 months it is far too early to identify Social Communication Difficulties as a condition — this is a window for gentle observation, not diagnosis. What is healthy and expected to emerge in these months are warm eye contact, social smiles, cooing back-and-forth, and brightening at familiar faces and voices. If several of these social cues seem consistently absent across days and settings, that is simply a reason for a reassuring developmental check — not a cause for alarm.

What is appropriate to observe at 3–6 months

Social Communication Difficulties (ICD-11 6A01.22) is a label that becomes clinically meaningful much later, once a child is using gestures, words and back-and-forth interaction. In a baby this young, you are simply watching how the early building blocks of connection are coming along:

What you'd love to see emerging

• Looking at your face and holding eye contact during cuddles and feeds
• Social smiles — smiling in response to your smile or voice
• Cooing, gurgling and early vocal "replies" when you talk to them
• Settling or brightening at a familiar voice or face
• Following your face or a toy with their eyes

Gentle things to keep an eye on (over weeks, not a single day)

• Rarely making or holding eye contact during close, calm moments
• Not yet smiling back socially by around 3 months
• Very little cooing, gurgling or vocal turn-taking by 5–6 months
• Seeming consistently hard to engage or soothe through face and voice

Babies have sleepy days, fussy days and quiet temperaments — one off day means nothing. It is only a persistent pattern across many days and people that is worth mentioning to a professional.

When a check becomes wise

There is no "diagnose now" at this age. Book a general developmental check if, over several weeks, your baby shows very little social smiling, eye contact or vocal response — or simply if you feel a quiet worry. Trust that instinct; early, reassuring conversations are always worthwhile, and most babies who start a little slow simply need a little more time.
