What's happening?

Childhood trauma, officially called Adverse Childhood Experiences (ACEs), is a group of preventable harms that happen to someone whilst they are a child and leave a lasting impact.

Although not everyone who experiences childhood trauma will go on to develop problems, ACEs are linked to an increased risk of lifelong poor health (physical and mental), lower educational achievement, addiction and substance abuse, and also becoming involved in crime and violence1.

The previous Welsh Government pushed for adoption of a “trauma-informed approach” by public services. This means being aware of different types of trauma and recognising that anyone they come across may have experienced it2.

On 1st July 2026, the Senedd unanimously agreed a Member’s Debate motion welcoming work to address ADEs in Wales to date, but calling for increased awareness of trauma by public authorities (particularly the Senedd Commission).

Why is this happening?

Some common forms of Adverse Childhood Experiences include:

  • Bullying.
  • Domestic and sexual abuse.
  • Growing up in a dysfunctional household (i.e. parents with addiction or mental health problems).
  • Being a young carer.
  • Experience of care services.
  • Homelessness.
Who has been affected?

According to Public Health Wales, 47% of adults in Wales have experienced at least one childhood trauma, with 14% experiencing four or more.

Plaid Cymru
  • Supports trauma-informed policy
  • Opposed
  • Neutral/No Opinion

Plaid Cymru backbenchers have come out in support of a trauma-informed approach to policy, pointing to successful local examples of this approach working.

The grooming of children and young people by adults for the purposes of sexual abuse is one of the most insidiously harmful and abhorrent crimes in society. I'm pleased that Plaid Cymru has committed to ensure that both learners and educators are fully informed on how to recognise and report signs of grooming through professional training and through RSE, relationships and sexuality education. Recognising harmful relationships and behaviours is a key part of RSE, and it has the potential to play a significant role in lowering the rates of adversity and harm for children in Wales.
Beca Brown MS
Beca Brown MSGwynedd Maldwyn
If we're serious about supporting young people to reach their potential and to thrive, we must not only support them, but recognise the trauma they've experienced. Without the recognition and support, an adopted child can be left with trauma, poor mental health and behavioural issues.....What we need to see is recognition of previous trauma and the support that goes alongside it….On top of this, I'd really like to see the unique status of adopted people legally recognised, so that the support can be put in place.
Kiera Marshall MS
Kiera Marshall MSCaerdydd Penarth
I would like to use my contribution to highlight the progressive work that's already being done in my constituency….In practice, this means placing an extra emphasis on supporting the well-being of our children and young people, through outdoor activities, for example; it means ensuring that there is a shared language for understanding trauma, and that that is used across public services in the county; and it means empowering local community groups to contribute to programmes that shape the future of their local areas.

Reform UK
  • Supports trauma-informed policy
  • Opposed
  • Neutral/No Opinion

Sarah Cooper-Lesadd MS (at the time, a Reform UK MS) made a particularly powerful contribution, highlighting her personal experiences of going through the care system. She supported calls for greater trauma-awareness in the public sector.

My birth mother died when I was three weeks old. She had postnatal psychosis, a severe, frightening and treatable condition, and she did not get the help she needed in time. Today, with her history known, she might have been seen before crisis ever came, supported through pregnancy, monitored in the weeks that followed, kept safe. She fell through every gap the system had, and the highest price was paid by her and by a three-week-old baby, me, who entered care because the mother who loved her could not be saved.
Sarah Cooper-Lesadd MS
Sarah Cooper-Lesadd MSPen-y-bont Bro Morgannwg
The difference between a care-experienced child who thrives and the one who does not is rarely talent, and never worth. It is about whether someone in the system chooses to see them. And this is what trauma-informed practice means—not a slogan, not a toolkit gathering dust, but a culture in which the midwife, the teacher, the nurse, the social worker are equipped to see the person, not just the case.

Labour
  • Supports trauma-informed policy
  • Opposed
  • Neutral/No Opinion

Labour MSs highlighted work the previous Welsh Government had done in introducing a trauma-informed framework in the public sector.

I would encourage all Members to look at the (trauma-informed Wales) framework....It's based on four practice levels: trauma aware, trauma skilled, trauma enhanced and specialist interventions. Trauma aware applies to everyone and focuses on developing a basic understanding of trauma and adversity, recognising their impact and responding with compassion, empathy and respect.

Conservatives
  • Supports trauma-informed policy
  • Opposed
  • Neutral/No Opinion

The Conservatives called for better long-term funding support for charities working in the field of childhood trauma.

.....organisations delivering essential trauma-informed services should not have to spend so much time worrying about whether they will still exist the following year.... So, I wonder, in the Cabinet Minister's response, whether she would consider whether longer term funding arrangements could be introduced for charities such as (Stepping Stones) and, on the multi-year funding where appropriate, whether that would provide greater stability, allow organisations....to plan ahead....rather than continually bidding for short-term funding grants.

Jane Dodds focused on preventing ACEs through stronger laws on child protection and children’s rights.

I hope we can think about what we can do (to) prevent ACEs wherever we can. That means, for me, investing in families early on, before they reach the crisis point, through strong early years services, parenting support and tackling child poverty. It also means embedding children's rights into every decision that we make. Last year, myself and other Members in the Senedd at the time, and cross-sector, developed Bil pob plentyn, a Bill for every child, which was about making sure that children's interests were paramount to every decision that we make.

Who is responsible?

Sioned Williams MS

Social Justice Minister

What have ministers said?
The cost of not doing so impacts not only the individual in terms of the lost opportunity to enjoy a long, happy, healthy and productive life, but is also felt by families, communities, public services and our economy. One study that looked at the financial cost of ACEs in England and Wales estimated that the annual costs were nearly £43 billion, equivalent to around £1,800 per household per annum. So, as well as a moral obligation, we have an economic imperative to act on ACEs.
Sioned Williams MS
Sioned Williams MSBrycheiniog Tawe Nedd
I do recognise….the importance of taking a cross-Government, system-wide, holistic approach to tackling childhood adversity and trauma, guided by the evidence and best practice. A commitment to working in an ACE and trauma-informed way is already embedded within Welsh Government policies, programmes and strategies, but I will continue to encourage and push for this as new policies and programmes are developed, and to ensure good practice is continued and shared.

What do the Welsh Government want to do?

Plaid Cymru didn’t include any specific commitments around childhood trauma in its 2026 manifesto.

However, some pledges are partly related to this. These include commitments to improve child safeguarding standards and mental health services for new mothers.

Nothing new has been announced by the Welsh Government. The Minister supports a trauma-informed approach, particularly the guidance provided by the existing public sector ACE Hub. 

Does this need a new law or regulations?

As things stand, no.

How long will this take?

The public sector ACE Hub was introduced in the previous Senedd term, and the Welsh Government already has (to an extent) embedded trauma-informed policies.

The Senedd Commission has agreed to consider how it can improve its own duties in this area – but no timescales have been provided.

What have the Senedd's Committees said?

Nothing has been discussed yet.
