C'mon, folks. It's a poem about a little baby. Seriously! Sure, we're guessing that sex played a part in the baby's journey into the world – but, after going through labor, we're not sure that the speaker in this poem would want to remember that right now. In fact, she's bound and determined to make sure we all know just how "cow-heavy" and less than sexy she is at this particular moment.
You could think of this poem as instant birth control. After all, do you really want to spend your life in a Victorian nightgown, waiting for your kid to wake up? We didn't think so.
