Can a lactating woman donate blood?

There are conflicting opinions about donating blood while breastfeeding. The US Red Cross okays blood donation for nursing moms after 6 weeks postpartum. Donating blood causes a small loss of blood volume (and therefore a loss of fluid), so there is a theoretical possibility for a short-term temporary reduction in milk supply. Moms with vulnerable supplies may want to avoid donation. In general, women who are not pregnant, have good iron levels (that will be tested before donation), are not taking antibiotics, and are at least 100 pounds are good candidates for blood donation.
