A mum-of-two from Merthyr said she was called "paranoid" for years before her seven-year-old daughter was diagnosed with autism.
Natasha Evans said her daughter Miley was diagnosed with ADHD at four-years-old following disruptive behaviour at school. But Natasha said she disagreed with the diagnosis.
Natasha had to research Miley’s behaviour herself to try to understand it.
Natasha is now trying to raise more awareness of autism and the support available.
Natasha has now become the chair of the Merthyr branch of the National Autism Society.
