Donating blood while breastfeeding
I have donated twice while nursing. The first time my baby was 8 weeks. Afterwards, I got really dizzy and sick and it took a day or so to recover. I think it had more to do with giving birth recently and low iron levels. My supply was not affected. The second time my baby was about 8 months and it went fine. I made sure to hang out afterwards and eat a cookie and get some juice and I was fine. My supply was not affected this time either.
