well a lot of it is normal behavior, but it wont hurt to speak to your doctor I have seen children eat off their nail polish they do not have any disorder, either that or they pick it off with there finger nails .May I ask what the other non food items are ?
Good suggestion, teddybear. Be to google PICA when researching it. Teddybear accidentally typo-ed an extra C in the spelling.
See a doctor, because that is not normal. It sounds like she has PICCA. That is when people are drawn to eat things that aren't food.
