We were dead set on getting a 3D/4D scan done. We ended up going with the ULTIMATE PACKAGE which costs $235.00 but includes two visits and all the extra's. We had our first one done at 16 weeks to try and get the gender determination, but the baby was uncooperative so they tldl us to come back again 2 weeks later and they would do another one for free. It was the best experience ever! We got great pictures, found out we are having a girl, and are very please with the results! It is pricey, but well worth it I think. We have our final 3D scan scheduled at 30 weeks (when the baby is nice and plump so we can see her features really well).
Talk to your doctor first! I switched doc's mid pregnancy and had my first appointment with them 2 weeks ago. The doctor said, "We use a 3D ultrasound machine at our facility." I was like, "NO WAY! Are you serious? I just paid $200.00 to have that done!"
So....bad news is if I would have found my doctor sooner I would not have had ot pay for the 3D images...but oh well right?
Also...doctors really frown upon those U/S places because they are not really doctor's that run those places, only certified ultrasound technicians. Nothing wrong with that, just be prepared to get a lecture from your doctor on the accuracy of the 3D scan performed. My doc said I would probably find out a different gender than what the U/S place saw...but I think the docs are just haters. :)
Here is a pic of the 3D scan we had done at 17 1/2 weeks.....
