3D SONOGRAM

So we found out we’re having our third boy!! Anyone who had a 3D sonogram feel a little disappointed with the services? When I went for my appointment I was under the assumption that the entire sonogram session would be 3D. Most of it was 2d and then some shots were 3D. I would say 90/10. Is this what you guys experienced as well? I’m excited to have see my munchkin and experienced it. I just thought paying that much for the sonogram it was a full 3D. Experience.
