It's caused by two maturing developments coming together: a secure attachment to you and growing object permanence — your baby now knows you still exist when out of sight and wants you back. It needs reassurance, not treatment, and settles as your child learns you always return.","answer_md":"*The moment your baby clings, cries, and reaches for you the second you step away — that's not a problem to fix, it's a milestone to celebrate.*\n\n## In short\nSeparation anxiety in a young baby is a **normal, healthy stage of emotional development** — not a sign that anything is wrong. It usually begins around **6 to 8 months**, peaks between **10 and 18 months**, and happens because your baby has grown clever enough to know you are special and to notice when you are gone. It is caused by two beautiful developments coming together: a deep, secure bond with you, and a growing memory that lets your baby realise you still exist even when out of sight.\n\n## Why it happens\nIn the early months, a baby largely lives in the present — out of sight is out of mind. As the brain matures, two things change:\n\n- **Object permanence** — your baby learns that you continue to exist even when they can't see you. So when you leave the room, they now *know* you're somewhere else, and they want you back.\n- **Attachment** — your baby has formed a strong, trusting bond with their familiar carers. Preferring you, and protesting when you go, is the natural flip-side of that secure connection.\n\nAdd a developing memory and a new awareness of strangers, and you get the classic clinginess, crying at handovers, and reaching back for you. It tends to feel stronger when a baby is tired, hungry, unwell, or in an unfamiliar place — and it gradually settles as your child learns, again and again, that you always come back.\n\n## What helps\nThis stage doesn't need treatment — it needs gentle, consistent reassurance:\n- Practise short, cheerful goodbyes; long, anxious ones make it harder.\n- Always say bye and return on cue, so trust builds.\n- Play peekaboo and hide-and-seek — joyful rehearsals of \"you go, you come back\".\n- Leave your baby with familiar, warm carers and a comfort object.\n\n## The Pinnacle way\nDevelopmental measurement supports care planning; diagnosis requires an appropriately qualified healthcare professional., under qualified clinician care — separation anxiety at this age is a typical milestone, not a condition to label.
