I don't do baby talk because I just don't like it. Not to babies not to animals.

I do find baby talk irritating, but to each their own. As long as they don't say anything to me for no baby talking I won't say anything for those who baby talk.

But I will just say that I'm under the impression that baby talk is done more for the talker wanting to talk like that, rather that for the listener to have a easier understanding, as I was always understood the same without baby talking and just trying to use simpler words for smaller kids but without that cartoon voice.
