Baby doesn't move

I've had 3 ultrasounds, one at 20 weeks, one at 25 (3D/4D), and the most recent today at 28 weeks(3D/4D). Each time, baby is head down facing my spine. We haven't been able to get a good face pic of baby. I feel this kiddo kicking all day, but apparently he never changes position. I'm not concerned, just frustrated. I was always under the impression that babies flipped themselves up, down, sideways, etc throughout the pregnancy, and settled into one position when they were ready to be born. Has anyone else experienced this?
