Protect regular one-to-one time with each sibling and let them voice every feeling, even resentment; explain autism age-appropriately; and if they help care for your child, ask the council for a young carer's assessment.
Start with protected, regular time
The single thing siblings tell charities they miss most is your attention. When one child's needs fill the house, the others learn to ask for less. So pick a small, repeatable slot that belongs to each sibling on their own: the school run, a Saturday breakfast, ten minutes at bedtime. The detail that matters is that it is regular and protected, not grand. A predictable ten minutes beats an occasional day out.
In that time, let them say the hard things. A sibling may feel jealous, embarrassed, frightened or guilty for feeling any of it. The National Autistic Society suggests offering more than one way to talk, because some children find it easier to write a note or send a text than to say a feeling out loud. You do not have to fix the feeling. You have to let it be said.
Explain autism in words they understand
Behaviour that goes unexplained gets taken personally. A younger sibling who is told nothing may decide their brother hits because he is naughty, or that their sister ignores them because she does not care. An honest, age-appropriate explanation, repeated as they grow, turns a confusing home into one that makes sense. Scope has parent-facing guidance on being open about disability and watching for the moment a sibling starts taking on too much. If you want help with the words themselves, see how do I explain autism to my other children.
If they help care, name them as a young carer
This is the part most advice skips. A child under 18 who provides, or intends to provide, care for someone else is a young carer. If your child helps with their autistic sibling, for example by supervising, soothing meltdowns, or helping at bedtime, they have a legal right to a free young carer's needs assessment from your local council. Under section 96 of the Children and Families Act 2014, the council must assess when a young carer appears to have support needs, or when the young carer or a parent asks. Two points the soft blogs miss:
- You can request it. The assessment is not gated behind how much or what kind of care they do, and a parent can ask for it, not just the child.
- The council should look for them. Local authorities have a duty to take reasonable steps to identify young carers in their area, so you can also ask why yours has not.
Alongside the statutory route, connect them to peer support. Sibs is the UK charity for siblings of disabled people; its Young Sibs service supports children aged 7 to 17 directly, on any sibling issue.
