What's in my belly?

Who is using What's in my Belly (whatsinmybelly.com) for baby guesses? We find out what we're having next week (current predictions are 77% girl!) and we've been having SO much fun getting people to make their predictions.
It's basically Fantasy Football for babies. People guess gender, hair color, eye color, length, weight, date and time of birth. They collect points for correct guesses. It's so fun!
