Early treatment is key when treating children and young people with mental health problems, Health Minister Mark Drakeford has said.
On Friday he announced an extra £7.6m a year would be invested to improve services.
The money is an 18% rise on last year’s £42.8m Child and Adolescent Mental Health Services (CAMHS) budget.
Last year, Mr Drakeford announced a review of the service after childcare experts told BBC Wales it was in crisis.
