Judy, the best reason I ever heard was from Linda Smith. She tells of a new mother who complained of being tired all the time. She went to a physician who told her she needed a pacemaker. The mother got a second opinion who told her she did not need it. She decided to do it anyway and was told to wean because the breastmilk would short out the pacer. (Maybe Linda can tell the story better than this. I nearly wet my pants the first time I heard her tell it--it's a lot more fun to listen to than to read--especially all the comments we make). Oh, the fun we have in Ohio..... Martha Grodrian Brower RD LD IBCLC Class Clown
