About SW. I don't know her at all but to me, she does look like a person who put certain faith in "natural" things. If these parents take their kids to doctors too often, it is not Munchausen by proxy. It is probably new natural remedy. If such parents harm their kids, it is not through physical harm; they are merely over trusting "natural" things as opposed to medicinal drugs. Psychologically, such parents are, in fact, very concerned about their kids, but occasionally put too much faith into unproven remedies. This I can imagine about SW, but maybe I am mistaken. In short, if someone told me SW was concerned about vaccines or "leaky gut", or antibiotics, I would not be surprised. But physically harming her kids, choking them? Give me a break!
I apologize if I am wrong here, I am trying to understand the nature of frequent doctor's visits.
