Hi, I looked into this as I was a frequent donor for many years. Once baby is 6months old it's considered ok, even if you're still breast-feeding - you just need to stay hydrated. When I went tho I couldn't donate as my iron levels were low, not anaemic, just low - presumably from feeding lo. I was told they'll call me back at the next session but the lady did say she wouldn't be surprised if they were still low. Not much help but some info perhaps!
