Since becoming pregnant, one of the things that has really bothered me the most has been my crazy heightened sense of smell. In the cafeteria where I work, I can't even go into our walk-in cooler to get food out, and even though my morning sickness has mostly subsided, it comes back in full-force when I smell the aromas of the kitchen.
For this reason, I have decided to quit my job, and my kind boss moved me to the checkout line instead of actually cooking food until my last day.
A third-grade boy noticed my absence from the behind-the-counter-scenes and asked me, "why haven't you been cooking the food as much?" I replied that "I'm having a baby, and sometimes it makes me feel a little sick." The third-grader got a solemn look on his face and tried to be sympathetic. "Oh," he said, "I know what that's like."
Another fun story that I adore, though it didn't happen to me:
"I was expecting my second child. One day, after a particularly unpleasant bout with morning sickness, my small boy asked, 'Mommy, is the baby in your tummy making you feel bad again?' I didn't feel inclined at the moment to have a conversation on the topic, so I replied with a simple, one-word answer: 'Yes.' Unfortunately, my son required more explanation when his next question came: 'Then Mommy, why did you eat it?'"
