While I do agree, that this woman shouldn't be teaching this stuff if she is not educated enough to know risks, and YL needs a higher level of standard for their instructors, however, as a breastfeeding mother it is your responsibility to know what you need to know before adding anything new to your system - that goes for anything in general not just EOs.
You knew right off the bat that she wasn't well qualified, why did you trust her with that response when you didn't trust her to teach the class?
You felt the burning and irritation, you knew something wasn't right. I would have ended the class right there and said sorry, I'm nursing. I'm sorry your little boy is sick, I hope you received the proper care or he worked through it.
I do not do RDT, and I don't know how much stock I put into it. I have taken the YL classes and have enjoyed them. I have seen and felt the benefits of YL over other brands I have tried - but I haven't tried EVERY EO brand so I can't say YL is the best - just the best I have used.
