i read your post title and my first thought was "how awesome to be still going strong at 19 months" good on you. I BF DS til 14.5 months and then he self weaned which was so sad for me, whereas most of my friends thought i would be happy!
By and large most people still don't have a great understanding of the importance of BF andnits benefits so try not to let it bother you (it can be hard though i know) if you ever want that pat on the back and bells and whistles ( which you deserve) i'm sure there are heaps of people on here ready to give it to you. You're doing a great job and should be proud of yourself, you are certainly not "odd" for continuing to nourish your child the best way possible :)
