i personally wouldn't do a Liver Flush if i were nursing under any conditions. i don't care that people say that 'the baby is fine.' Liver Flushing is a process not just of releasing physical toxins, but also of releasing emotional toxic patterns, from what i've experienced. i wouldn't do it while i'm breastfeeding a baby. i'd do something gentler like eating better and cutting out eating all Sugar and rotten stuff. i'd concentrate on eating really well, and getting as many nutrients into the baby as possible.
releasing toxic sludge and old toxic emotions seems like too much for a newborn. just my 2 cents.
