A 4-year old autistic girl in Britain has a rare addiction that makes her eat up carpets and fabrics.

With doctors unable to treat her addiction, Charlotte’s mother, Nikki, is worried that one day a fabric might get clogged up somewhere and kill her daughter.
Stating that she and her husband, Alasdair, are alone in the fight, Nikki said, “Alasdair and I work hard, but there is no help out there. We can't afford to replace the sofas or the carpet because there's no assistance for working parents. We want to make people aware of the condition because it is rarely publicized. Some people make me feel as if Charlotte is a freak but she is my daughter and I would do anything for her.”
