OMG, I can't believe it's already that time. My 20 week u/s is tomorrow! I'm a little nervous that the kids are going to be antsy during it, but I'm working on getting together a bag of things for them to do. The 2 older ones I'm not so worried about, but Cadence is still at that stage where sitting just doesn't happen. I really hope the baby cooperates so we're able to see the sex and get all the measurements and pictures quickly.
