From our friends at the Here Be Monsters podcast: Marlo Mack gave birth to a son. At least, she thought she did. But her son crawled towards dresses, wanted to be a princess, and asked to grow long blonde hair. At age 3, Marlo's son asked to go back into mommy's tummy, so he could come back out as a baby girl. Marlo thought it was a phase--it wasn't.
