I used it with my second. I'm not convinced of the benefits, since the research out there shows a pretty minimal benefit overall, but I like drinking it and I'll do it again. Anecdotally, my second labor was much easier than my first, but my first was back labor and the tea probably wouldn't have done much for that. But either way, I'll start it in the late second, early third trimester.
