Barnardos is calling for more medical staff to tackle growing waiting lists for children's healthcare.
The charity says there is been a 44% increase in waiting lists for mental health assessments.
Children are having to wait almost a year on average for disability assessments.
Over 10,000 children are waiting for speech and language therapy.
June Tinsley from Barnardos says such delays can create long term problems: "For verbal communication and verbal reasoning, infancy and early childhood is a key time.
"So any delay has knock on effects on a child's ability to communicate and it impacts on their life, not only today, but into the future."
