Pica Disorder
Some medical conditions have peculiar names and you’ve probably never heard of them.
Pica Disorder Almost all young children like to put things in their mouth, but for some it could be the start of a serious problem. Pica disorder is the persistent eating of non-nutritional substances like dirt and paint.
Adding to the trouble of trying to cure the disease is that many of the objects being eaten could lead to poisoning, infections and digestive trouble.
The Handbook for Clinical Child Psychology supports general behavioral strategies as the best way to treat the disease. [source: Your Health]
