A six-year-old sitting in an accident and emergency waiting room, hours from any specialist mental health support, is no longer the exception it once was. New figures show that emergency departments in England are absorbing a surge of young children in acute psychiatric distress, at a scale and speed that has caught paediatric leaders off guard. Between 2019 and 2025, attendances for mental health crises among children aged six to nine rose by 62 per cent, from 3,870 to 6,269. For a cohort barely old enough to articulate what they are experiencing, that increase is not a statistical curiosity. It is a signal that something in the system meant to catch children early has failed to do so.

The rise is not confined to this age group. Figures obtained through a Freedom of Information request by the Royal College of Paediatrics and Child Health show that mental health attendances among all children and young people aged six to seventeen climbed by 36 per cent, reaching 75,491 in 2025. Eating disorders and self-harm feature prominently among the presenting crises, conditions that typically develop over months or years before reaching the point of hospital admission. Their presence in these figures suggests that community and primary care routes, which should be identifying and treating these conditions long before crisis point, are simply not keeping pace with need.

What happens once these children arrive in hospital compounds the problem. The data show a 217 per cent increase in children waiting more than twelve hours for appropriate mental health support after arrival, and a 514 per cent rise in those left in accident and emergency for more than 72 hours. These are not figures that describe occasional delay. They describe children, some barely out of infancy, held for days in an environment designed for physical trauma and acute illness rather than psychiatric care, often without access to age-appropriate therapeutic support.

Dr Ronny Cheung of the Royal College of Paediatrics and Child Health has warned that young children are particularly vulnerable to this kind of prolonged exposure, given how sensitive early neurodevelopment is to environment and stress. His argument extends beyond clinical concern into economic reasoning: children who do not receive timely intervention are at greater risk of falling out of education and, eventually, employment. That is a warning aimed less at clinicians than at Treasury officials weighing the long-term cost of a system that treats prevention as discretionary rather than essential.

The Department of Health and Social Care has acknowledged the scale of the problem and points to the rollout of 150 community-based mental health hubs alongside school-based support teams, with a further strategy expected this summer. These interventions are a reasonable start, but their pace does not yet match the trajectory of demand shown in the RCPCH figures. A single summer strategy is unlikely to reverse a trend that has built steadily over six years.

The emergency department crisis is, in truth, the visible edge of a much larger backlog. The Children's Commissioner recently found that more than one million children had an active mental health referral in 2024-25, nearly double the number recorded in 2018-19, with anxiety accounting for the majority of cases. Seen against that figure, the rise in hospital attendances looks less like a discrete emergency and more like the point at which an overloaded referral system stops absorbing pressure and starts releasing it, into the one part of the NHS that cannot turn a child away.

For policymakers, the implication is straightforward even if the remedy is not. Community and school-based services need to expand at a rate that matches referral growth, not merely acknowledge it. Without that shift, accident and emergency departments will continue to function as a de facto first line of mental health care for children, at considerable cost to both the children involved and a hospital system already stretched thin.
