Field day at clinic

My mother is a radiologist . I was getting bored at home yesterday so i went to her clinic with her. It was amazing what i saw. She was doing an ultrasound of a lady pregnant with a 5 month child (i think) and it was just.....just unbeliveable. I saw his heartbeat, him move his hand and foot. I saw him shake his head and then he fell asleep !! <3 it was really really absolutely amazing....
