Siblings in Care: The Bond the System Too Often Breaks

For many young people in residential care, the most durable relationship in their life is not with a parent, not with a keyworker, and not with a foster carer. It is with a brother or sister. Sibling relationships predate any placement, are not contingent on a professional decision, and in most cases will outlast the residential setting by decades. A sibling is, in the most literal sense, someone who shares your history — who was in the same house, who remembers the same things, who does not need the context explaining. For children whose early lives have involved significant relational disruption, that shared history is not a small thing. It may be the most continuous thread they have. The way the care system treats sibling relationships does not always reflect this.

The evidence on siblings in care is consistent and has been building for some time. Young people who maintain meaningful contact with their brothers and sisters show lower rates of placement breakdown, better emotional wellbeing, and stronger long-term outcomes than those whose sibling relationships are severed or become infrequent. Some of this is likely selection effect — placements stable enough to allow regular contact are also placements doing other things well. But the relationship itself appears to have independent value. Siblings offer a particular kind of validation that adult carers cannot replicate: the knowledge that someone who shares your origins also knows who you are, and has chosen, within whatever constraints the system imposes, to remain connected to you.

The statutory duty to promote contact between siblings is clear enough. The Children Act 1989 and the Children and Social Work Act 2017 both speak to it. What is less clear, in practice, is what happens when placement availability, local authority geography, and competing care plans all push in different directions. A sibling group separated not by considered professional judgement but by the absence of a home able to take more than two children together. Contact arrangements recorded in a care plan but dependent on a social worker who has a caseload that makes quarterly visits to a child's sibling feel like a logistical ambition. Two children placed in different local authority areas whose contact is nominally promoted but practically reduced to a video call scheduled two weeks in advance by people who have never met either of them. The gap between the duty and the delivery is not a gap in legislation. It is a gap in capacity, coordination, and genuine prioritisation.

Sibling relationships are also not uniformly straightforward, and it is worth being honest about this. The dynamics that develop in households where children have experienced abuse, neglect, or serious instability are often complex. One sibling may have played a protective role — parenting others, absorbing harm on their behalf — in ways that generate guilt and obligation rather than simple affection. Allegiances formed in adversity do not always translate cleanly into the more ordinary sibling territory of shared interests and uncomplicated companionship. Some children have witnessed or experienced harm from their siblings. Not all sibling contact should be promoted, and a reflexive insistence on it can obscure real dynamics that need careful thought. The task is not to maintain contact regardless, but to think seriously about what each sibling relationship is actually like for each young person — what it gives them, what it asks of them, and how it can be supported in a form that is genuinely beneficial.

What distinguishes homes that do this well is not a specialised therapeutic model. It is attentiveness. They pay attention to how a young person is before a sibling visit and after it. They notice whether contact leaves a young person energised or unsettled, and they think about what that might mean rather than logging it as a neutral observation. They advocate — at reviews, in conversations with placing authorities, in the way they write reports — for sibling contact to be treated as a priority rather than a variable. They treat a sibling visit as an event that deserves preparation and space, not a logistical task to be cleared from the calendar. And when contact is complicated, they hold that complication with the young person rather than resolving it by reducing contact to the point where the relationship quietly fades.

The residential home cannot create a sibling relationship that did not exist. It can only protect the ones that do. A young person placed far from their siblings, in a home that does not think of sibling contact as part of its remit, is a young person whose chance of maintaining one of the most important relationships in their life is diminishing month by month, without anyone necessarily intending that outcome. Residential care at its best holds a young person's whole life in view — not just the placement, not just the current care plan, but the longer story that preceded the placement and will continue beyond it. Siblings are part of that story. Treating them as peripheral is a category error.
