oh, well we had some of that too Dude, when you put it that way. We used "num-nums" for all food, bottle, breast and foods when they started, snacks, etc...but also, like you are saying, you're using "regular words" then the cute "baby" word. A few of the mispronunciations we let slide too because they were just cute, especially when jumbled up in a more advanced sentance.
It also sounds like you were very tuned in to what she needed and was trying to communicate to you. That's special smile Not all parents are "listening", kwim?
I get excited when the library lets me know my books are ready for pickup...
