Fungal infections, including yeast, can grow in the moist area between the foreskin and glans. The solution is washing. Girls, with a greater area of inner moist surfaces, are more likely to get yeast infections than boys. For both, good hygiene is the preventative. Every time he bathes, have him pull back his foreskin as far as it will go, but without hurting himself, and rinse with clear water, and return his foreskin to its normal position.
If the foreskin becomes red and itching, a common cause is a fungal or yeast infection. It is easily treated with a prescribed anti-fungal cream, or at home with liquid acidophilus culture (available in health food stores) applied 6 times daily for 6 days. Stop bathing with soaps and bubble-baths.
CAUTION: Never forcibly retract (pull back) his foreskin or allow anyone else to do so! It is painful, and can lead to infections and adhesions. Stay with your boy during all medical examinations, and state that his foreskin should not be retracted. Your son should be the first and only person to retract his foreskin.
