If the stories told were accurate, then these professionals did cross boundaries and were innapropriate in their conduct. An LC making recommendations regarding the care of a 33 week neonate is beyond her scope of practice. There are good and bad in every area, thats why moms should get a doula or an LC who has the appropriate training and references.
That said, I wish the NYT realizes how many women benefit from a good doula and a good LC. I am sure they will get plenty of letters disputing this article, maybe it will encourage them to write something to balance the negative protrayal they describe in this article.
