I have a "cat voice" that I use with my critters which could be considered "baybee talk", but I don't subject other people to it. I don't even mind using "kiddie" ways to pronouce something with my sisters like the "PAsketti" (I think we all had ways of saying spaghetti)or even saying I have to go poopy or go night night, when I am being a bit silly. What I HATE is when an adult "goes into character", much like they are an actor on a stage who is playing the part of a 2 y/o, and their demeanor, body language, and every single word uttered and the tone is baybee talk, like my inlaws do. They will actually do this for hours at the time, when the youngest grandbrat is in the vicinity, with FEW breaks in between. They will do the goo goo ga ga shit, get a response from him, and then longingly look my way for a laugh or nod of approval at how "cute" the whole thing is NOT. They nearly FORCE you to laugh with them and if you do not, they will be offended or WORSE, they will keep doing it over and over and over, like someone who repeatedly tells a bad joke to solicit laughter, until they get the response that they want.
Talking to the kyd that way is annoying enough, but when they look directly at me across the dining room table and say, "Duz Aunt Kim Kim want some of TJ's Banilla puddin' cake? or Did Aunt Kim Kim make a smiley plate?, and the kyd is already in another room playing, is where I draw the line on what's ANNOYING. I have been around people who did the baybee talk thing my whole life and it never really bothered me too much UNTIL I met these people (inlaws). It has to be because they speak that way among themselves and to me that drives me nuts. It's ridiculous and there is just no sense in it and I am wondering JUST how long they will keep it up since he is almost four years old.
