I can understand the baby thing as a fetish and agree with some difficulty in accepting it. But, I can not compare infantilism and CDing.
After all, I did not object, get upset, call her a lier, tell her family or file for divorce because my wife wore pants, slacks, suits, shorts, flats or sneekers every day, including wearing some of my clothes and shoes. Being a "typical" modern woman, she wanted to be "comfortable" in her dressing and only wore a skirt or dress to weddings or funerals.
