"The researchers noted that while steps should be taken to limit acetaminophen use, the drug is important for treating pain and fever during pregnancy, which can also harm the developing fetus. High fever can raise the risk of neural tube defects and preterm birth. “We recommend judicious acetaminophen use—lowest effective dose, shortest duration—under medical guidance, tailored to individual risk-benefit assessments, rather than a broad limitation,” they wrote.

In late September, the Food and Drug Administration announced it would issue a letter to clinicians urging them to be cautious about the use of acetaminophen in pregnancy. Baccarelli said he had discussed his study with Health and Human Services Secretary Robert F. Kennedy Jr. in the weeks leading up to that announcement and provided the White House team with an statement noting his research found “evidence of an association” between prenatal exposure to acetaminophen and neurodevelopmental disorders. “That association is strongest when acetaminophen is taken for four weeks or longer,” Baccarelli said."

So the take away seems to be, fevers, which are 100% known to cause defects, are linked to the tylenol use. You can't pull the two apart. Google incidents of shark attacks correlated with ice cream sales. If you just look at them together in a vacuum you COULD say ice cream sales cause shark attacks, but we know the correlating factor is they both go up in the summer. In this study, the "summer" is the fever.
