Names of kids

I was in Chipotle, wondering why my integration by parts was not working when I received the second call within 15 minutes from my sister:

sis: Why didn't you answer my first call - where are you -
ft: I -
sis: What are you doing in May?
ft: I'll be here, at Charm City U.
sis: Oh, well, I wanted to tell you that you're going to be an Uncle again!
ft: Name him "v du".
sis: No.
ft: I -
sis: Are you coming home for Thanksgiving?
ft: Will there be 800 dollars stuffed in the Turkey?
sis: Oh, baby's crying take care. Bye. Love you.

Maybe she would have liked "u dv" or "u v" better.
