I'm so sorry that this article struck a raw nerve for you, mama. I didn't read the article, myself, but I would guess that it highlighted that BM is a really powerful weapon against NEC. BM is not foolproof, however, as I provided only BM to my 25 weeker who got NEC, anyway.
For me, I find that resources of information on preemie conditions are often meant to be objective, but my emotional baggage clouds things up sometimes. For example, when I read about pre-term labor, I feel stupid and agitated because I didn't know what was happening to me when I went into labor with my DD at 24 weeks. So, I find myself getting anxious and upset at the articles when the reality is that the issue is with me. I don't know if this is the same for you, but I just wanted to share.
