Extra Ultrasound Today

We had ultrasound number two today, since our little daughter-to-be was not positioned very well when we went in the first time. All is very well. What was most interesting is the midwife switched the machine to 3D mode. I have seen 3D advertised at private clinics, and wondered why we didn't normally receive this. Today we did. I still question why they generally stick to the regular imaging.
