Everybody looks adorable! I can't wait to have a bigger bump!!
Here's me at 18w with twins. Still nothing much to report. But, I'm tall (5'10"), retroverted uterus, long torso....lots of room to grow. I didn't show appreciably with my last two singletons until about 26 weeks and well past 30w with my first. I'm sure I'll be plenty huge in the end

Oops the pics were huge, so I'm just linking!
First one. And a
second one, you can see that my uterus is high...a good hand's width above my belly button....so plenty 'big' just hiding LOL
