Miller points out that the letter writer’s request could be hard to abide by.
“First, “no smelly foods” is a much broader category than “no peanuts.” And “smelly” is in the eye of the nose-holder; it’s not always possible for you, let alone your colleagues, to anticipate which foods will trigger heaves. (If you develop an aversion to hot coffee, I don’t like your odds.)”
I know that for many women, their food aversions change through the course of their pregnancy as well.
Miller also advises that while the letter writer thinks these changes will only need to be in place ‘for a few weeks,’ morning sickness can occur throughout an entire pregnancy.
