My 11 year old DD has always been really fussy about clothes and prefers to wear the same thing until it disintegrates. She wore her school skirt and shoes at weekends when she was tiny and won't let me wash things as it makes them 'itchy and smaller'. I have just managed to wash her bed clothes today as her bed was a pit and I knew it would lead to a massive meltdown when she went to bed. She shouted at me when she realised everything was clean! There are American websites and help groups but it doesn't seem to be a thing in the UK. She has worn the same vest for weeks now and also hates nail-cutting and haircuts. Not sure how much to force the matter as obviously don't want her to be bullied or get scrofulous skin disease!
