(DAILYMAIL) — A mother has to keep her five-year-old daughter locked out of the kitchen at all times – because a rare condition means she could eat herself to death.

Ava Carvey has Prader-Willi syndrome (PWS) which leaves her constantly hungry meaning the family kitchen has to be kept behind bars.

Her mother, Marika Carvey, 35, has to keep Ava on a strict low calorie diet to prevent her overeating.
