I had to say, all is not lost when a BF teenager goes astray.  I was the same
kind of teenager you mentioned.  I also dropped out of high school (went to
college at sixteen) and had a child (that I breastfeed) earlier then my
mother hoped  (at 18).  Then I went back to college when my first child was
two.  That liitle rebellious teenager, that I was, grew up to earn her
Masters in Nutrition and raise three healthy boys- all brestfed.
