This is a healthy sign of bonding, not a disorder. It typically peaks between 9 and 18 months and eases as your child grows in confidence.","q":"Is it normal for my 6-month-old to cry every time I leave the room?"},{"a":"No. Separation distress is a normal, expected part of development at 6 to 9 months, so a clinical diagnosis of Separation Anxiety Disorder is not meaningfully applied to a baby this age. Anxiety diagnoses become relevant much later, when fears are persistent, out of step with age and clearly disrupt daily life.","q":"Can a baby this young be diagnosed with Separation Anxiety Disorder?"},{"a":"Speak to your paediatrician or a developmental team if your baby does not seem to recognise or prefer familiar caregivers, shows no social smiling or eye contact, cannot be comforted by you when upset, or is missing other milestones like babbling or responding to sounds.

Watch instead for whether your baby recognises and is comforted by you and is meeting broader milestones; if not, seek a general developmental check. Any diagnosis is formed only at a Pinnacle centre under clinician care.","answer_md":"*If your little one cries the moment you leave the room and clings at the sight of a stranger, your heart may sink — but at 6 to 9 months, this is very often a sign of healthy love, not a disorder.*\n\n## In short\nAt 6 to 9 months, becoming upset when you leave and wary of strangers is a normal and *expected* developmental milestone — your baby has learnt that you are special and that you still exist even when out of sight. [Separation Anxiety Disorder](/separation-anxiety-disorder) (ICD-11 6B05) is a clinical diagnosis that is not meaningfully applied to a baby this young, because separation distress at this age is part of typical bonding. So the honest answer is: this is almost never a reason to worry — it is a reason to feel reassured that attachment is developing well.\n\n## What is actually happening at this age\nAround 6–9 months, most babies pass through a beautiful leap in understanding called *object permanence* — they begin to grasp that you continue to exist even when they cannot see you. This naturally brings:\n\n- **Crying or fussing when you leave the room** — even briefly\n- **Clinging or reaching** for you when others approach\n- **Wariness of strangers** or unfamiliar faces\n- **Settling quickly** once you return or are nearby\n\nThis is healthy separation *anxiety* — a sign of a secure bond — not a *disorder*. It usually peaks between 9 and 18 months and gently eases as your child grows in confidence that you always come back.\n\n## When a check is genuinely sensible\nRather than worrying about a diagnosis at this age, it is far more useful to keep a gentle eye on your baby's overall development. Speak warmly with your paediatrician or a developmental team if you notice your baby:\n\n- Does **not** seem to recognise or prefer familiar caregivers at all\n- Shows **no** interest in faces, eye contact or social smiling\n- Cannot be **soothed or comforted** by you when upset\n- Is missing other milestones — babbling, responding to sounds, sitting with support\n\nThese point towards a *general* developmental review, not a separation-anxiety assessment. A clinical anxiety diagnosis becomes meaningful only much later in childhood, when fears are persistent, out of step with age, and clearly disrupt daily life.\n\n## The Pinnacle way\nDevelopmental measurement supports care planning; diagnosis requires an appropriately qualified healthcare professional., under qualified clinician care — never from an online form or a checklist. Our team looks at your baby's whole story — bonding, communication, play and milestones — through a warm, strengths-based lens. If you would like reassurance, a gentle [developmental check](/developmental-screening) or supportive [child psychology guidance](/child-psychology) can help you understand exactly what to expect at each stage. You can also learn how our [AbilityScore® assessment](/ask/what-is-the-abilityscore-and-how-is-it-calculated) works.\n\n## Trusted sources\nWHO ICD-11 (6B05, Separation Anxiety Disorder); American Academy of Pediatrics guidance on infant social-emotional milestones and stranger/separation anxiety (healthychildren.org); WHO Nurturing Care Framework on responsive caregiving.\n\n**Next step —** If your baby's clinginess feels normal but you simply want reassurance, that is a perfectly good reason to ask. [Book a gentle developmental check](https://www.pinnacleblooms.org/enroll-autism-speech-aba-therapies-india) with a Pinnacle clinician.\n\nThis is general information, not a diagnosis — individual assessment and diagnosis require an appropriately qualified healthcare professional.","canonical":"https://pinnacleblooms.org/ask/when-should-i-worry-that-my-6-to-9-month-old-might-have-separation-anxiety-disorder","editorial":{"reviewed_at":"2026-06-11T20:12:18.613642+00:00","reviewed_by":null,"developed_by":"SETU Consortium · Pinnacle Blooms Network"},"alternates":[{"href":"https://pinnacleblooms.org/ask/when-should-i-worry-that-my-6-to-9-month-old-might-have-separation-anxiety-disorder","lang":"en","indexable":true},{"href":"https://pinnacleblooms.org/ask/when-should-i-worry-that-my-6-to-9-month-old-might-have-separation-anxiety-disorder-te","lang":"te","indexable":true}],"dimensions":[{"key":"conditions","label":"Conditions"}],"meta_title":"Separation Anxiety in a 6-9 Month-Old Baby","meta_robots":"index, follow, max-image-preview:large","everyday_tip":"Play peek-a-boo and simple hide-and-find games — they playfully teach your baby that things (and you) come back.
