A Word for Each Pair of Teeth

If language is a virus (per William S. Burroughs, Laurie Anderson and Neil Stephenson) then Sylvia is getting an infection. I currently count four words in her vocabulary, one for each pair of teeth teeth.

"Mama", the first, comes as no surprise.
I suppose it's only fair that the person who gave birth to her gets a word.

The second, "baby", is also reasonable since Sylvia happens to be one.

Being one of her favorite toys, as can be seen below, we can give up the third spot to spherical toys.

But, it comes as bitter bile that the fourth spot does not go to the guy who had some part in her existence. Instead of "Poppa", "Dadda", "Papito", "Aba" or any other paternal description, Sylvia has struck upon "Cat" to fill her quiver of words.

Cleo, in 2003, upset that Brick is
not paying her adequate attention.

But I'm not bitter. Poppas are tough and don't need recognition.
