Since birth, my baby has had toubles with his hemoglobin(red blood cells that were smaller and less abundant than normal). He became anemic, was put on iron and now his red cells are fine. However, the doctor mentioned at our nine month check-up that his white cell count was "a little" low and has been for awhile. She never mentioned anything about his white cells before and i'm wondering what could be the cause of the low count. Except for a couple of minor colds and a clogged tear duct (that just recently cleared up) he's been very healthy. Is this something to worry about? Can a low wbc count occur without an underlying medical reason, and is it ever known to resolve itself without medical intervention?
