I don't know about how it affects nursing but I can say that my experience with valerian was erratic. Sometimes it really helped with anxiety attacks, sometimes it didn't. For sleep, sometimes it worked wonderfully, other times it left me very groggy in the morning.
IIRC, the published research does suggest that it needs to be used daily for at least a month in order to really help with anxiety. I didn't use it that way, because my periods of anxiety tend to last only 2-3 weeks.
