Supporting the Siblings of a Child with Developmental Regression

When one child needs extra care, their brothers and sisters are quietly watching, wondering, and needing you too — and there's so much you can do to help them feel safe and loved.

In short

Siblings of a child with developmental regression often carry big feelings — confusion, worry, jealousy, even guilt — that they may not have words for. You support them best with honest, age-appropriate explanations, protected one-to-one time, permission to feel everything, and small ways to be part of the family team without being burdened by it. Brothers and sisters who feel seen and included tend to grow into remarkably caring, resilient people. You don't have to be perfect — being present and open is what matters most.

Ways to support the siblings

• Explain in words they understand. Tell them, simply and truthfully, that their brother or sister is having some trouble with skills they used to have, and that kind doctors and therapists are helping. Reassure them it is nobody's fault — not theirs, not their sibling's.
• Make space for every feeling. It's normal for a sibling to feel sad, angry, embarrassed or left out. Let them know all those feelings are allowed, and that loving someone and finding things hard can both be true at once.
• Protect one-to-one time. Even 15 unhurried minutes a day that belong only to them — a story, a walk, a game — tells a sibling "you matter just as much."
• Give a small, joyful role, not a job. Let them help in light, fun ways they choose, but never make them a substitute carer. Keep their childhood theirs.
• Keep their world steady. Friendships, school events, hobbies and their own celebrations deserve to continue. Predictable routines are deeply reassuring.
• Watch for the quiet ones. A sibling who becomes "too good" or withdrawn may be hiding worry. Gentle check-ins and naming feelings for them can open the door.

When to seek extra help

If a sibling shows lasting changes — trouble sleeping, slipping at school, frequent tummy aches, persistent sadness or anger, or pulling away from friends — it's worth talking to your paediatrician or a child counsellor. Sibling support groups and family sessions can also be a wonderful relief, reminding children they are not alone.
