Just a second.  It does not follow that it is the breastfeeding that
caused the problems with her teeth.  In Quebec, I heard the
expression:  "On perd une dent avec chaque enfant".  "You lose a tooth
with each baby", except it rhymes in French.  And Quebec has the
lowest rate of breastfeeding in Canada and has had for a long time.
