I'm all for people deciding what they do or don't want to eat, but this story is particularly tragic, and raises some disturbing issues.

The breast-fed infants of two mothers who did not eat any animal products, including milk and eggs, developed brain abnormalities as a result of a vitamin-B12 deficiency, the US Centers for Disease Control and Prevention (CDC) reported Thursday.

Now, if a woman fed her child skim milk for several weeks, instead of formula, and the child developed health complications and developmental abnormalities, would she be criminally liable?

Even if she were doing so, not with malicious intent, but out of ignorance, does this constitute child abuse?
