Summary: Why do parents with similar IQs give birth to babies with high and low IQs? Pregnant mothers should pay attention to exercise during pregnancy, which is beneficial to the development of the fetus. The fetus\’s intellectual development is good and its IQ will be higher. Yaoyao was already 35 years old when she gave birth to her son by caesarean section, and her postpartum recovery was very slow. Although Yaoyao has a high IQ and is a doctoral candidate, the child she gave birth to is a bit stupid and has a low IQ. The doctor also said that the child is mentally retarded. Looking at Yan Yan\’s son, although Yan Yan was just an ordinary undergraduate, Yan Yan got married after graduation and became pregnant soon, so Yan Yan was relatively young when she gave birth to the child.
