It will therefore be seen that vulvovaginitis is a calamity, and everything possible should be done to guard female children from contracting it. _All_ children should _always_ sleep alone. Under no circumstances should a child sleep with anybody else, be it a sister, a mother, a friend, a governess, or a servant girl. People should be very careful in sending their children to spend a night or two with some friends. The friends may be all right, but still a friend of the friends or a relative of the friends may not be. I have known several cases where the origin of the vulvovaginitis could be traced to little girls spending a week at the house of some friends where a boarder or relative was infected with gonorrhea. That children should be kept away from associating or playing with adults or other children who are known to have gonorrheal infection goes without saying. The child's genitals should be frequently inspected by the mother, and scrupulous cleanliness by frequent bathing, sponging with warm solutions and powdering, should be maintained. The toilet seats in school should receive special attention. The wooden seat is a menace because it often harbors gonorrheal pus from either the female or male genitals, while the only proper seat is one of the so-called U-shaped style, that is, one in which the front is entirely open, like the letter U.
