As I'll be going for my fourth scan in a couple of weeks, I checked with the sonographer. As she pointed out, a study of 40 people is far too small and all the best people are left-handed. She is, I am... I'll be more than happy if Liebling is. Everything is developing perfectly and is just as it should be (no damage done!).

I'll be having 9w, 13w, 19w, 21w and maybe 34-35w (depending on how the placenta is lying in the next scan). Most people here just get 12w and 21w scans.

There's been an endocrine study recently that shows low birth weight babies can have similar problems - diabetes, brain troubles... - anyway, low birth weight can be caused in part by extreme stress, which can be caused by a high risk pregnancy which would mean more ultrasounds: maybe it's not the ultrasounds that cause it, just the "high risk" factor instead?
