(WKBW/ABC) Researchers in the United Kingdom have found that fetal nutrition can have a big impact on your baby's IQ.
They looked at identical twins and found that the twin who weighed more at birth, had a higher verbal IQ score than the lighter twin, showing that proper nutrition in the womb is vital to a child's development.
They say that improving the nutrition of undersized children *after* birth showed no effect on the brain.
