Sure why not stop for fluorescein dye. You need a microscope to see it in the retina for crying out loud. If it got into the milk in signficant amounts, the milk would be green. Demand information from the opthalmologist which shows this stuff gets into the milk in significant amounts. Until s/he can provide it, assure the mother that the dye is fine. The ignorance of these people is highlighted by their saying the mother needs to stop for three days. Can they explain this. Are they telling us the half life of this stuff is 12 hours or so (5 half lives to virtual complete elimination?). Breastfeeding is too important for the mother and baby to allow its sacrifice on the altar of some opthalmologist's ignorance. I am in a foul mood today. I ask indulgence and forgiveness for any excess. But I am just sick of people telling mothers they can't breastfeed, without any evidence that this is the case, and then *we* have to run our butts off trying to prove its okay to breastfeed.
