Children with Developmental Language Disorder (DLD) are as able and healthy as their peers. With one primary exception, they have difficulties thinking about, understanding and using language. A child with DLD will not develop language skills in the typical way and there is no obvious reason for this difficulty. There may be no outward signs of disability and no obvious physical indication of a problem. For this reason, DLD is also known as a ‘hidden but common disability’ affecting 1 in 14 children.
