Not childless. I have 10 great nieces and nephews, so I have participated in the "potty-game". I guess limited because the men in the family aren't usually involved in "the game". Maybe chidlren's potties wihtin the bathrooms of each sex? But I suppose that would only apply to older kides (3&up). Or as my roomate has suggested "family" bathrooms(cross-sex), similar I guess to the concept of unisex. Never seen them before but I suppose they would work. Good dialogue.
