Melissa - thanks so much for your responses, and pointing out the photos it helps to see a photo of a baby in it.

I don't know the degree yet, the click seems to have been audible occasionally when the doctor has checked on two occasions and the leg creases look even so hopefully coverage is not too bad, just know the left is worse than the right. It is a bit frustrating at the moment because have to wait for my doctor to review the results and give me a referral when I know we do have to do something and the ultrasound guy said would be good if can see someone next week (the sooner the better and all that). I would feel so much happier if had an appointment for next week.
