Angie,
Congratulations! What great news to start the new year!
I can totally understand where your head is at right now. I'm currently 29 weeks pregnant with #3 - also a SURPRISE! And I can't help with names - we didn't find out the sex of this baby, and we're still completely stumped for names. Well, we do have some ideas for girls, but we've already named 2 boys and are running out of ideas for that side of things.
As for the nausea, it's awful isn't it? Ginger in many forms works for some, seasickness bands (that you wear like a bracelet) work for some, vitamin B6 supplements work for some. I hope you feel better soon. I found the exhaustion in the first trimester to be especially rough, too, since I'm home with my 2 very active boys. Not much time for sleeping when they're running around!
Again, congratulations!
Katie
