Now it’s time for a lesson in “bubble math.” Bubble bath equals soap. Soap plus skin equals dryness. Dryness equals itching. Itching equals irritation. No bubble bath equals no irritation. It doesn’t matter whether the bubble bath comes from the health food store or the supermarket; it will dry out Lucy’s skin no matter what. Worse yet, bubble baths also dry out little girls’ vaginas. The dryness leads to itching, which creates a characteristic vaginal irritation and discharge. Stop the bubble baths, and the problem disappears.
