A record two million children in the UK are experiencing issues with their speech and language, according to Speech and Language UK.
And one in five children and young people aged eight to 25 experienced a mental health problem in 2023, according to the NHS.
Speech and Language UK's chief executive Jane Harris says children who struggle with talking and understanding words are more likely to develop poor mental health.
"Everyone uses words to identify how they're feeling. If you're struggling with language, you can't say to yourself, 'I'm sad, I'm angry.' You can't categorise how you're feeling," she says.
"So if we've got more and more children who are struggling with language, we're going to end up with more and more children with mental health problems."
The charity wants better training in speech and language for teachers and school support staff, as well as mental health professionals, and better information sharing between schools and mental health teams to spot language issues in children at an early age.
In a joint report with the Centre for Mental Health, the authors call for schools and mental health teams to move away from a reliance on talking-based therapies, adding that solutions like art therapy could sometimes be more appropriate.
