Are you my shweetie pie? My pookie-ookums? My gweat big bwog weaduh?*
My father used to laugh about a married couple he knew and imitate the wife calling her husband "Shnookles" in a whiny voice.... "But, Shnooooklessss..."
I'm not a fan of the baby talk. Not with sweethearts. Not even with babies.
I can remember a coworker bringing his toddler in to the office one day and talking to her in a ridiculously loud, repetitive, and silly voice of the "WHO'S DADDY'S GWEAT BIG GIRL? YOU ARE! YESH YOU ARE, WOOGUMS! YESH, YOU ARE!!" variety. Yeech. It's the kind of thing where you wish the child would haul off and bitch slap the father.
I can't imagine that this kind of patterning helps with the child's speech development. And I find that loud parents beget loud children. And, nobody wants that. But I imagine when you have a small child you have to find something to do to entertain yourself.
A lot of people drop into baby talk with their animals and, 'though still goofy, I find this slightly more tolerable. With babies and with animals, at least one can make the case that the change in voice might be getting the baby's or animal's attention.
But, enlighten me: Why do adults do this with each other? Do you do this? Do you know sweethearts that do this in front of you? Are speech impediments way sexy?
* Well, are you?
