I have gotten it with both of my daughters and thought it was absolutely amazing and a thing to treasure. Its a little peek at them before they are even born and although you can kinda see what they look like it doesn't take away from the moment when you actually meet them and see what color hair and eyes they have and feel their skin.
I have gotten it done with all three of my daughters. It is the most amazing experience to get to see your baby in the most secret and sacred place; the womb. You will only have one chance to see them like that and even having the technology to do that is AMAZING. We were very satisfied with getting our 3D/4D sonograms and felt it was worth every penny.
My dr did 3D he didn't ask but really you don't know completely till you see baby what they look like u/s doesn't do it justice
See I just want it to be a surprise who's forehead(his family is norweign) the baby has and who's nose and ears. But he says u can't see that just don't have to see the other stuff to see the baby. Idk. I had a friend who's bros gf got one and it looked just like his son.
I loved mine! It's something amazing to put in her baby book. I was very anxious to see how she looked also but the majority of the reason was to see her gender to be sure!
