Is there a reason for her seemingly insatiable appetite for dirt, or is it something that she will grow out of. Honestly, I feed her a balanced diet every day. It simply refers to the ingestion of nonnutritive substances and, in children of your daughter's age, dirt is often the substance at issue. This condition is often, but not always, associated with various types of mental retardation. Sometimes there is a particular reason for the ingestion, but often this is not the case.
Some children have a decreased number of red blood cells, a condition called iron deficiency anemia.
This sometimes results in a child's displaying pica by ingesting dirt. Your daughter's pediatrician can readily determine if she is anemic by a simple blood test. Treatment for such anemia is iron, and when the level of red blood cells is normal the pica disappears. If not, please do so. He can check to see if there is a medically-based reason for the behavior, and also if she has been poisoned y lead or contracted any parasite due to the ingestion of dirt.
