Many conditions we recognise now were not recognised then. In my 40s I was diagnosed as dyxpraxic, the same time as DS was dignosed. As a child I was just seen as clumsy, careless and lazy in the sense that my writing and needlework were poor because I was seen as unwilling to concentrate and really make an effort to do things neatly and tidly. I am also 90% sure I have ADHD, although, as yet, no formal diagnosis.
As a child I was 'Fidgety Phil who can't sit still'. the child who never paid attention because her mind was elsewhere, who was always talking, either unable to concentrate or hyper concentrating. constantly in trouble for speaking out of turn.
ADHD was first identified as such in the early 20th century, but not well known until the 1980s but dyspraxia was not identified as a specific problem until the 1980s.
I am sure there were many other children like me, from the number of adults I have met exhibiting similar behaviours.
I was attended a convent grammar school. There was a girl in my class with epilepsy, petit mal, and another girl who was deaf. In the year below there was a girl with learning disabilities. I believe her mother was close to the nuns. She was well behaved in classes and attended well and at times seemed to know a lot about odd little corners in the history and geography syllabus. Everybody accepted her and were kind to her.
