My Dr. didn't tell me to do anything but I will probably drink a lil caffeine before hand because all of my friends have said they did and they were able to see the goods!!
I didn't eat or drink anything...And he was so active because he was hungry. A bit too active since we now have to go back so they can do some other measurements but we did get a good look at his little man parts
Every US dept seems to do things differently. I wasn't given any eating or drinking instructions. Halfway through, we thought if I emptied my bladder, the baby might have more room to stretch out, so I did and we were able to get the leg and foot measurements we needed.
Mine is scheduled for next Tuesday, and I wasn't told to do anything beforehand. It's at 8am so I'll eat breakfast and have a little bit of caffeine before.
