I found this article online. http://www.telegraph.co.uk/health/healthnews/5286670/Morning-sickness-increases-the-chance-that-child-will-have-high-IQ.html In case you don't want to read this, this is the title and gist of it.
Morning sickness 'increases the chance that child will have high IQ'
Women who suffer morning sickness during pregnancy may be more likely to have a child with a high IQ, according to new research.
I don't care if it is true or not I am all for articles that help morning sick pregnant women feel better about their pregnancies. It would be nice to have a formula that equates the IQ increase per vomit so that you could finish puking, flush, and say "well I just increased this child's IQ by 10.3 points.
