Autism has no easy answers

For those who desire motherhood, pregnancy is a privilege. But that joy can be tinged with feelings of anxiety and guilt, given a roiling sea of bans, strictures, guidelines, recommendations and advice. Yes to folic acid supplements but be wary of dairy. Farewell, pinot noir and pate; hello, pelvic floor exercises.

Now, a new grenade has landed. On Sept 22, US President Donald Trump declared that pregnant women should

avoid Tylenol, a branded, over-the-counter pain reliever

that contains acetaminophen (the same ingredient is called paracetamol outside North America), because of a possible link with autism.
