Morning Sickness linked to higher child IQ

Researchers have found that among 121 children between the ages of 3 and 7, those whose mothers had suffered morning sickness scored higher on average, on certain IQ tests, memory and language skills.

The findings also suggest that nausea and vomiting in pregnancy is not harmful and in fact may enhance children's long-term mental development.

Nausea and vomiting during pregnancy is quite common, especially during the first trimester as it is related to changes in particular hormones that are needed for the placenta's development.

Past studies have also linked morning sickness to lower rates of miscarriage, stillbirth and preterm delivery.
