AbilityScore® is part of Pinnacle’s developmental assessment. Diagnosis, where needed, requires an appropriately qualified healthcare professional.","answer_md":"*When one child carries developmental trauma, their brothers and sisters carry quiet weight too — and they deserve to feel seen, safe and loved just as fully.*\n\n## In short\nSiblings of a child with developmental trauma often grow up fast, worry silently, and sometimes feel invisible while attention flows to their brother or sister. You support them by giving them **honest, age-appropriate explanations, one-to-one time that is truly theirs, permission to feel every emotion, and a steady routine that tells them they are safe too.** Looking after siblings is not a luxury — it protects the whole family's wellbeing and, in turn, helps your child with trauma heal in a calmer home.\n\n## Ways to support the siblings\n- **Name it simply and honestly.** Children sense tension even when nothing is said. Explain, in words that fit their age, that their sibling's brain and feelings are still learning to feel safe after hard early experiences — and that it is not their fault, and not anyone's fault.\n- **Protect one-to-one time.** Even ten unhurried minutes a day that belong only to them — a story, a walk, a game — tells a sibling they matter just as much. Predictable special time matters more than grand gestures.\n- **Let all feelings be allowed.** Siblings often feel love *and* jealousy, loyalty *and* resentment, guilt for being \"the easy one\". Welcome these honestly: \"It's okay to feel cross sometimes. You can always tell me.\"\n- **Ease the helper role.** Many siblings quietly become little carers. Let them help in small chosen ways, but make clear that being a child — playing, resting, having their own friends and interests — is their real job.\n- **Keep routines steady.** When trauma responses make home unpredictable, a reliable bedtime, mealtime and weekend rhythm gives siblings an anchor of safety.\n- **Give them their own outlet.** A trusted teacher, grandparent, sibling-support group or counsellor offers a safe place to speak freely — especially as they grow older.\n\n## When to seek extra support\nIf a sibling becomes persistently withdrawn, anxious or angry, struggles at school, takes on adult-sized responsibility, or starts saying they are \"the bad one\" or \"don't matter\", it is wise to seek guidance. A short conversation with a clinician can help the whole family — siblings included — feel steadier.\n\n## The Pinnacle way\nThis is general guidance, not a diagnosis — a clinical AbilityScore® and any diagnosis are formed **only at a Pinnacle Blooms Network centre, under qualified clinician care.** Our family-centred approach supports the whole household, not one child alone. Explore how we work with families through [Pinnacle Blooms Network](/), learn how a child's strengths are profiled in our [structured clinical assessment](/ask/what-is-the-abilityscore-and-how-is-it-calculated), and see how [behaviour therapy](/behaviour-therapy) builds calmer, safer family routines.\n\n## Trusted sources\nWHO and Nurturing Care Framework guidance on family wellbeing and responsive caregiving; American Academy of Pediatrics (HealthyChildren.org) resources on sibling support and family resilience; CDC guidance on supporting children after adverse early experiences.\n\n**Next step —** Want a plan that supports your whole family, siblings included?
