Congrats R2F!
My wife and I are expecting our first child, a little girl in late September! My wife's at 23 weeks now, so if you have any questions, we'll have already "been there, done that", so we'll be happy to help! Did you hear the heartbeat yet? That's an awesome experience as well!
That website is cool with the weekly updates! We get it too every week. We decided not to get the 4D however. We figure that we'll meet her in 4 months anyways....so we can be patient! (plus..more money for me to fly!!!!!)
Cheers,
Sime
