a thick white discharge, appearing at the foreskin is quite normal for boys under the age of 3 years. These basically are epithelial 'pearls", a medical term for skin that is shed. We normally shed skin from the outer layers all over the body, in a small boy, due to the foreskin being relatively closed, the skin collects and forms these white discharges. If it becomes associated with pain, or redness
or burning during passing urine, please get his urine examined for infection. But if he is well and none of the above symptoms are present, please be reassured that this is a part of his growing up !
