No need go on the offensive. If the poster had experience, I wanted to hear about it. I don't need experience to err on caution.

There is no compelling reason for him to do frequent ultrasounds on a developing baby.

My point was that you're trying to base your argument not on evidence of the safety of sonogram machines but rather on the credibility of the "messenger". I don't have experience just as a blind man can't tell if the sky is blue, but that doesn't mean the color of the sky is disputable. "There are no substantiated side-effects documented in studies." It is pointless to debate "experience," you wouldn't take your doctor's opinion as "absolute" just as I don't take my professor's anti-Bush statements to be absolute either...

Therefore, there is no compelling reason for him NOT to do frequent ultrasounds on a developing baby, but you chose to attack him anyway...
