I realize Chris will belittle me again and Ty will come up with some counter link, but how do you explain this? From Johns Hopkins, no less: "The researchers analyzed data from the Boston Birth Cohort, a 20-year study of early life factors influencing pregnancy and child development. They found that children whose cord blood samples contained the highest levels of acetaminophen—the generic name for the drug Tylenol—were roughly three times more likely to be diagnosed with ADHD or autism spectrum disorder later in childhood, compared to children with the lowest levels of acetaminophen in their cord blood."
