im currently 23 weeks and I want to get a 3D picture of my daughter but she always moves around. I have to be seen every month to make sure that she is growing and to keep an eye on the placenta. so every month I can get 3D since it's free any secret on how to get her to not move so much or have her sleepy lol last two times have been a fail because she's so active she's always moving around and kicking when we do the ultrasound.
