How do you guys do it?

I am amazed at how confident you guys are at guessing gender by nub. I am pregnant with my 4th child, and I still don't know what I'm looking for!!!! It's great seeing the guesses, and how many guesses are the same. I can't wait to post my 12 week scan pic in a couple of weeks to see if any of you can guess. I've already posted a 6 and 8 week scan pic for the ramzi theory, but don't think that's as popular as the nub theory.

After I saw Dr. Ramzi guess wrong on several ultrasounds it became hard for me to buy into it any more.

Nub def. more accurate and if you wait till late in 12th or even into 13th week for your scan it is even more accurate.
