I'm SO with you on the baby talk! We never did that either. Frankly, GT or no, I don't get why anyone does it.
The only exceptions are when our DSs would mispronounce something and they was cute and funny. DS7 was obsessed with trucks, so when they went by, he'd call out "Tuck! Anuna tuck!" and it was so cute that we still do it. Similarly, DS4 called pinapple "apple people," so we still call it that.
I think those are the only two examples of anything other than real words that we ever used with the kids. But how could we not?
