Perhaps you, like me, have always sought to parent with an emphasis on frankness regarding the human body and its natural and normal functions, without shame and with acceptance and appreciation for the wide variety of shapes, sizes, and colors. Perhaps you have always, in private settings, permitted honest observations about the differences and similarities of our bodies, encouraging a dialogue about function over form and of the very subjective and changeable nature of the term "beauty." Perhaps, during your recent pregnancy, your children were encouraged to observe the growth of your belly and even the existence of your stretch marks, so as to foster a sense of normalcy and acceptance regarding the biological functions of the female body, and of the cosmetic changes sometimes rendered by those functions.
Congratulations on being so forward thinking and relaxed and hippie-like and whatnot! Now your child, too, might pipe up with any or all of the following questions and observations (if you're lucky, all within the span of a few days!) -"Why are your front teeth so big, Mom?"
-(while tenderly patting your face) "Hey, Mom, you forehead skin feels bumpy! Why isn't it soft like the rest of your face?"
-(after bursting in on you as you are exiting the shower) "Huh, Mom, your butt doesn't look the same as mine- yours is sort of SAGGY, isn't it?"
Humph. I think maybe it's time to emphasize the importance of diplomacy and tact over honesty, now.
