Always - check for pinworms. So common with our little folk. They look like tiny white threads - often easier to locate at night. I think this is because the worms migrate to the anus in the quiet of the evening to lay their eggs. Medication can be purchased at your local pharmacy to alleviate this problem - you might have to ask the pharmist as sometimes this item is stored behind the counter, but it usually does not require a prescription. Hope this helps ....
