My current nanny is an older lady who'd been doing personal assistant work for me for about 10 months. In that time, as I got to know her, I judged her to be the most maternal woman I've ever met.
Finally, I sat her down in my living room, sat across from her, and asked, "Do you think you could change a wet adult diaper?" The rest of the conversation evolved from that point. I explained to her how my infantilism is a coping mechanism and helps me relax, told her what I needed from a caregiver, and she agreed to try.
As you know from my previous posts, I've had other babysitters and nannies over the years. In a very real sense, I think God put this lady in my life at this time in my life. Not only is she the best and most enthusiastic carer I've ever had, she's also become a very dear friend. In that respect, at least, I'm truly fortunate.
