It may not be the prettiest part of pregnancy, but all that rushing to the closest trash can to throw up, thanks to the good ol' morning sickness, is actually good for your baby. Yes! Nausea and vomiting means fewer miscarriages and birth defects, along with smarter kids.
The studies conducted over a 20-year span by the Hospital for Sick Children in Toronto observed 850,000 pregnant women in five different countries to see if the most common pregnancy side effect (85 percent of women suffer from it) serves a purpose or has any effect on the child. Although it's not definite, the thinking is that the nausea is caused by hormones released from the placenta, most specifically gonadotropin, which kicks into overdrive when a woman is preggers.

It was found that moms who just couldn't stop puking up their meals had healthier babies, both in weight and length, and their risk for premature births decreased, too. Mothers who didn’t suffer from morning sickness had a 9.5 percent rate of having a premature birth compared to 6.4 percent of those mothers who did spend some of their pregnancy being sick to their stomachs. Miscarriages were found to be three times higher in mothers who had a smooth-sailing pregnancy, compared to those who suffered from the dreaded, daily upchuck factor.
Later on, when the children of the women were old enough to take I.Q. tests and really prove to the world how great the results of morning sickness can be, the kiddos whose moms really struggled to keep things down, had a higher I.Q., a greater grasp of language, and were just better behaved over all.
