Blue, if you read the first paragraph of the article, the baby was exclusively breastfed which means it ate no food, only breastmilk. So your argument that they fed the baby junk food is out. Also, they never sought medical care for their dying baby, which means they definitely never vaccinated. So your argument about vaccines causing the death are out.
The baby's only nutrition came from its vegan mother's body. And the baby never made it to its first birthday. You do the math.
