Extended breastfeeding.. *really!*
Not that I would breastfeed this long, but if you don't believe breasts are sexual, and if you do believe that breastmilk is incredibly nutritious, then... really, is there anything wrong with it? I don't think so. I love the innocence of these kids who say... "Breastmilk is the best thing in the world... No one should ever stop breastfeeding!"
