Early Signs of Separation Anxiety Disorder at 6–9 Months

When your baby cries the moment you step away, it can tug at your heart — but at this age, that protest is usually a sign of healthy love and growing awareness, not a disorder.

In short

At 6 to 9 months, separation distress is a normal and expected milestone, not a sign of Separation Anxiety Disorder. Around this age babies develop "object permanence" — they realise you still exist when you leave the room — so they protest, cry or reach for you when you go. A clinical label like Separation Anxiety Disorder (ICD-11 6B05) is not meaningful in infancy; it is recognised only later in childhood when fear is far beyond what's expected for age and disrupts daily life. So rather than watching for "signs of a disorder", this is the age to enjoy and gently support a healthy attachment.

What is normal — and healthy — at 6 to 9 months

What you may notice now is separation protest and stranger awareness, both of which are positive signs of bonding and brain development:

• Crying, clinging or reaching when you leave the room or hand her to someone else
• Becoming wary, quiet or tearful around unfamiliar faces
• Calming quickly once you return and offer comfort
• Looking for you, then settling and going back to play once reassured

These reactions usually peak between 8 and 18 months and ease naturally with time, gentle routines and consistent comfort. They show your baby has formed a secure, loving attachment to you — exactly what we hope for.

When a developmental check is wise

There is no need to look for an anxiety "disorder" at this age. A general developmental check is sensible, though, if you notice:

• Your baby seems hard to console even by you, much of the time
• Very little eye contact, smiling, babbling or interest in faces and toys
• Not responding to your voice, or seeming unusually still and unreactive
• Any loss of skills she previously had

These point not to a separation disorder but to broader development worth a gentle review. Persistent parental worry is always reason enough to ask.
