I am also breast feeding my bb. Just tell u the story of my brother. He is the only 100% breast feeding bb in our family. But he had to see the doctor every week when he was still a bb. The doctor finally has become a friend of our family la. So, I also support breast feeding but not 100% means that the bb will be very strong lor.
(I grow up by formula milk and my mother said I seldom saw the doctor when I was a bb arh.)
