Diagnosis, where needed, requires an appropriately qualified healthcare professional.","answer_md":"*When one child needs extra care, their brothers and sisters carry quiet feelings too — and they thrive when they feel seen, secure and special in their own right.*\n\n## In short\nSiblings of a child with a genetic or chromosomal syndrome do best when you give them **honest, age-appropriate information, dedicated one-to-one time, and permission to feel everything** — pride, love, worry, jealousy and guilt all at once. You don't need to be a perfect parent; you need to be an open one. Small, steady habits — a regular chat, their own special moments, a clear answer to \"why is my brother different?\" — build a brother or sister who grows up secure, kind and confident.\n\n## Ways to support a sibling\n- **Explain in words they understand.** Use the syndrome's name plainly and honestly, matched to their age. Children fill silence with scarier stories than the truth — clear, calm facts reassure far more than secrecy.\n- **Protect one-to-one time.** Even fifteen unhurried minutes that are *just theirs* — a walk, a bedtime story, a shared snack — tells a sibling they matter every bit as much.\n- **Let all feelings be okay.** Name them out loud: \"It's fine to love your sister and feel cross sometimes too.\" Unspoken guilt is heavier than spoken frustration.\n- **Don't over-burden the carer role.** Helping can build closeness and pride, but a child should not become a substitute parent. Keep their childhood theirs.\n- **Answer the big questions gently.** \"Will I get it too?\" and \"Whose fault is it?\" deserve honest, reassuring replies — and a clinician or genetic counsellor can help you find the right words.\n- **Connect them with others.** Sibling groups and peer meet-ups show a child they are not the only one living this life — a powerful comfort.\n\n## When to seek a little extra help\nIf a sibling shows lasting changes — sleep trouble, withdrawal, big drops at school, frequent tummy aches, or anger that doesn't ease — a chat with a counsellor or your paediatrician helps. These are common, workable responses, not signs you've done anything wrong.\n\n## The Pinnacle way\nFamily wellbeing sits at the heart of every plan, because a thriving sibling and a thriving family help the whole household flourish. AbilityScore® is part of Pinnacle’s developmental assessment. Diagnosis, where needed, requires an appropriately qualified healthcare professional — never from an app or online form.
