Lena, I'm in the same boat as you. You already know that I live in GA too, but my family (with the exception of my sister) live in VA and NJ. Besides visiting as much as we can (we've collected a ton of frequent flier miles) I keep pictures posted all around the house (bedrooms, bathrooms, mantle, refrigerator) of my immediate family, which includes my daughter's grandparents, uncles, cousins, aunts, etc. And even before she began speaking every time we would go to the refrigerator we would look at pictures and I would talk about the people in them and say their names. We also look at my scrapbooks so she can recall names and events. Then eventually she would start repeating what I said. Now, at three, she knows everyone by name and voice.
We're also great customers of MCI, and she talks to her Mimi and Grandad every couple of days, and the rest of the clan pretty often, as well. She talks to my sister almost every day. She especially likes to talk to her young cousins who are about the same age. The downside is that I can't keep her away from the phone.

Every time it rings she runs to answer it and gets very upset if we try to. It's a battle trying to rip the phone away from her. But at three years old, I'm learning that EVERYTHING is a battle these days. I'm finding that this is the toughest stage yet.
She'll get to know and love everybody because you do . . . don't worry.
Peace and blessings,
Kelli
