Congratulations!!
I too am a new Yorkie mom, although I don't yet have my little honey. We met him yesterday and put a deposit on him. He is 8 weeks old (unless he's only 6 wks, hope not, that is terrible by the way to be lied to like that). We too are trying to figure out a name right now. Before choosing our little guy, we talked about names and "Gracie" was on our short list for a girl. I am very excited as you are, what a great adventure! God bless your little one and watch over her. I too would be very nervous to have one so young, as I have no experience. There's alot of information here and lots of people willing to share their knowledge, you will do fine.
