Supporting siblings of SEND children: what every parent needs to know

Why you noticed at the kitchen table

Because that's where it leaks. Not in the appointments. Not at school, where the sibling will usually be doing brilliantly. At home, after dinner, when the adult attention finally has nowhere else to go.

Sibs, the UK charity for brothers and sisters of disabled children, estimates there are over half a million young siblings and more than one and a half million adult siblings in the UK living with this experience. (Sibs, About Sibs) They are the largest group of unrecognised young carers in the country. Most of them never call themselves carers. Their experience does not show up at school. It shows up in the kitchen, after the day has worn them down.

The work of the next sections is to name what your other child is carrying, in language specific enough to be useful, and then to be honest about what actually helps. Not the “quality time” line. The thing underneath it.

What is the specific sibling reality?

Four things, in different combinations, in almost every sibling of a SEND child: parentification, hyper-competence as performance, internalised guilt, and hidden grief. None of them look like trouble. That's the problem.

You will recognise some and not others. They sit underneath the surface behaviour, which can look like a model child, a child who has gone quiet, or a child who blows up over something small.

• Parentification. Your other child has picked up jobs nobody asked them to do. Helping at mealtimes. Watching for triggers. Calming their sibling down. Translating between their sibling and a confused adult. It looks like competence. It is competence. It is also a job a nine-year-old should not have, even when they say they don't mind.
• Hyper-competence as performance. They are doing well at school, polite at the kitchen table, helpful with the younger one. None of that is the same as being okay. It often means they have understood, very early, that being easy is the only available role.
• Internalised guilt. Guilt about being able to do the things their sibling can't. Guilt about being embarrassed in public. Guilt about being angry, then guilt about being guilty about being angry. A nine-year-old does not have words for any of this. They have a stomach ache instead.
• Hidden grief. Not grief for a death. Grief for the sibling relationship they thought they were going to have: the conversations, the play, the shared in-jokes. Or for the family life of a friend they visit, where one parent is not always on the phone to the council. This grief is real, it is ambiguous (no funeral, no permission to feel it), and most adults around the family do not have language for it.

The clinical literature has a name for that last one. Pauline Boss, an American family therapist, calls it ambiguous loss: the grief that exists when someone you love is still here but the relationship you expected isn't. You don't have to use the phrase with your child. It does help to know what it is.

What does the “glass child” framing mean?

It is a description, not a diagnosis. The phrase comes from a 2010 TEDx talk by Alicia Maples, the older sister of two disabled brothers, and it has spread because it puts a word to something most siblings recognise.

Maples described herself as a child the adults around her looked straight through, as if she were made of glass. Not invisible. Transparent. The light passed through her on its way to the sibling who needed the help. When the adults asked how she was doing, she remembers, she always said she was fine. The messaging she had absorbed by then was that adding her feelings to her parents' stress was not an option. (Alicia Maples, “Recognizing Glass Children”, TEDxSan Antonio, 2010.)

Sibs, the UK charity, hosts her talk and credits her with popularising the term. (Sibs, Glass Children) A few things to keep in mind when using it.

• It is not a clinical diagnosis. No psychiatrist will write “glass child syndrome” on a report. You will see the phrase “glass child syndrome” on some American wellness sites. That language is metaphorical, not medical.
• It is a useful word to describe the experience of feeling transparent in your own family. It is not a useful word to fix anything by itself.
• Some siblings of disabled people, including adult siblings, find the term reductive or do not identify with it. Use it as shorthand at home if it helps. Don't hand it to your other child as a label.

What do siblings actually say, and what do they mean?

They almost never say what they feel. They have learned what is allowed to be said in this house, and they say that instead. The gap between the two is where you can be useful.

The pattern under all of this is that siblings of SEND children learn very young to manage other people's emotional weather. Asked what they need, they will tell you what they think you can cope with hearing. Don't take the “I'm fine” as the answer. Take it as the start.

What actually helps?

Four things that work, in this order: named time, named feelings, peer connection, and accurate information about their sibling's condition. None of them is “family quality time.”

Named time

The thing that doesn't work is the abstract idea of spending more quality time together. It dissolves under the weight of a normal SEND week. The thing that does work is a small, protected, named slot. Fifteen unbroken minutes. Same time each day if you can, or the same anchor (after the bath, on the school walk, before bed). The phone is in the other room. The other child knows the slot is theirs and that you won't step out of it for a phone call from the council.

Sibs has been making this point in print for years. Contact, the UK charity for families with disabled children, says the same thing in their parent guidance: regular, predictable one-to-one time, however short, beats sporadic big gestures. (Contact, Supporting siblings)

Named feelings

You don't need to fix the feeling. You need to put a word to it. “You're cross.” “You're embarrassed and you're also a bit guilty for being embarrassed.” The most useful sentence in a sibling parenting toolkit is “You can feel two things at once.” Loving your brother and resenting him at 7:30 on a Wednesday are not contradictions. They live together in the same nine-year-old.

Peer connection

One of the heaviest things about being a sibling is that nobody else in your class understands. YoungSibs, which is run by Sibs, is the UK's online space for 7- to 17-year-olds with a disabled brother or sister. They can read other young people's stories, ask their own questions, and watch videos by siblings who get it. Many local authorities also run sibling groups through their short breaks team or their children's disability service. Ask your council's children with disabilities team what's in your area.

Accurate information

Siblings, including young ones, do better when they have honest, age-appropriate information about their brother or sister's condition than when they are protected from it. The reason: in the absence of accurate information, they make up worse information. They will assume it is contagious. They will assume they caused it. They will assume it's a secret you are ashamed of, so they should be too. A simple, factual conversation, repeated as they grow, prevents most of that.

When is your other child legally a young carer?

When they are under 18 and providing care to their sibling, regardless of how much or how often. If that's your other child, they have a right to ask the council for a Young Carer's Assessment, and the council has to do one.

The right comes from the Children and Families Act 2014, which extended young carer rights to all under-18s caring for someone in their family, including a disabled sibling. (Children and Families Act 2014, part 5, sections 96 to 97) The duty on the council is to identify and assess any young carer in their area who appears to have support needs, even if you haven't asked. The assessment looks at what your other child is doing, what they want their life to look like, and what support would help.

Real care tasks count. Helping with feeds, watching for safety, calming a sibling during a meltdown, helping with toileting, translating, missing time with friends because the family can't go. Emotional caring counts too. You don't need to be doing physical lifting to qualify.

The assessment is free. The Carers Trust has a clear, parent-friendly guide to what one looks like and what you can ask for. (Carers Trust, Young carers rights explained)

When should you seek formal support?

When the picture stops being “a tired child who needs more one-to-one time” and starts being sustained changes in mood, sleep, eating, school engagement, or self-talk. Siblings can and do develop their own anxiety and depression. The fact that the family already has a SEND diagnosis on file doesn't mean the other child can't need help too.

Warning signs to take seriously, especially if they last more than two or three weeks:

• Withdrawal from friends, clubs or activities they used to enjoy.
• Changes in sleep (waking, nightmares, refusing to go to bed alone).
• Changes in eating (skipping meals, secret eating, complaints of stomach ache before school).
• Self-critical talk: “I'm stupid,” “I'm a bad sister,” “it would be easier if I wasn't here.”
• School pulling you aside because their work or behaviour has changed, even slightly.
• Headaches, stomach aches, or other physical complaints with no medical cause.

Three routes, in order of how quickly you can use them.

1. School pastoral. Most primaries have a pastoral lead, family support worker, or ELSA (Emotional Literacy Support Assistant). Email the class teacher and ask for a short pastoral check-in for your other child. You don't need a diagnosis or a referral.
2. GP. Book an appointment for your other child specifically, on their own. The GP can refer to children and adolescent mental health services (CAMHS) where appropriate or to local lower-tier services such as school-based counselling.
3. Helplines and charities, while you wait. YoungMinds Parents Helpline on 0808 802 5544 for advice from a trained adviser. Sibs runs an email and information service for parents. YoungSibs gives your other child a peer space.

One thing to know about CAMHS in 2026: the wait for an initial appointment in most of England is months, not weeks. The referral is still worth making. While you wait, the school pastoral route and Sibs are doing the actual front-line work in most families.

What to do this week

Three things, in order of how much they will cost you.

1. Pick a fifteen-minute slot. Same time every day, or attached to a routine that already exists (the walk to school, the bath, the ten minutes before lights-out). Tell your other child this is their slot, by name. Phones in the other room. If you have to cancel one, name it and reschedule it, the way you would for any other appointment.
2. Sign your other child up to YoungSibs (if they're 7 to 17) and read Sibs' parent pages yourself. Twenty minutes. The single biggest information-gain on this whole subject in the UK is on those two sites.
3. If they are doing real care, ask the council for a Young Carer's Assessment. Email the children's services duty desk in your local authority. One line is enough: “I'm the parent of [name], aged [age], who provides care to their disabled sibling. I'm requesting a Young Carer's Assessment under the Children and Families Act 2014.” They have to respond.

And, in the slow time, sit with this. The sibling at the kitchen table is not a problem to be solved. They are a child who has been very, very good at being easy. The work is to make sure they don't have to be.
