Quoting Radame N Angela Robles:" My OB has the same advanced machine that does the 3d and at the beginning of my pregnancy around 12 weeks ... [snip!] ... we got a 3d since then i havent but im going again to see him the 31st i hope i get to see his face and see how hes changed"I love having an ultrasound at every appointment, it was odd thought because my youngest was the one using the machine when we spotted his face. Normally he hides. We were all in shock. That's all it took was a 5 yo to get it! My midwife lets them do the ultrasound so they are involved.
