These observations have sparked the interest of many researchers and psychologists, as children’s cognitive development is a crucial factor in shaping their future.
To address these questions, experts have conducted extensive research and surveys to identify the factors influencing children’s cognitive development.

Which is smarter, a baby born via C-section or natural birth?
From a brain development perspective, a newborn’s intelligence is not directly related to the birth method. Instead, a child’s cognitive development depends on various factors such as the mother’s health during pregnancy, genetic predispositions, nutrition, educational environment, and other factors.
There are clear medical indications for whether a C-section is necessary. For instance, if vaginal delivery poses a risk to the mother or the baby, or in cases such as a large fetus, abnormal fetal position, preeclampsia, or antepartum hemorrhage, a C-section is often the safer choice.
However, these decisions should be carefully evaluated by medical professionals. Choosing a C-section should be based solely on clear medical indications and not on reasons unrelated to health.
Otherwise, it may lead to unintended risks for both mother and child, causing more harm to the child’s body and health in the early years. Therefore, mothers should listen to and trust the advice of experts to ensure the best possible start for their children’s health.
Is it better to give birth during the day or at night?
According to research, there are notable differences between children born during the day and those born at night. The American College of Obstetricians and Gynecologists conducted a survey of the birthing processes of 429 women and found that the average length of labor for mothers who gave birth at night was approximately 40 minutes longer than those who gave birth during the day.
Longer labor durations increase health risks for mothers. Compared to daytime births, the risk of birth complications at night increases by 26%. This impacts the mother’s health and the child’s safety.
A mother’s health status during childbirth is intimately linked to the time of day. During the day, a mother’s physical condition is typically better due to optimal support from the medical staff.
In contrast, at night, many healthcare workers from different departments have finished their shifts, leaving only a few on duty. This reduces the efficiency of medical support, and in emergency situations, performing detailed checks on the mother and child in a timely manner may be more challenging.
Research indicates notable differences between children born during the day and at night.
Does a child’s birth weight reflect their IQ?
Aside from the method and timing of birth, a child’s weight is also a significant concern for many parents.
In reality, a child’s birth weight is somewhat correlated with their IQ, but it is not the sole determinant of cognitive development. Various factors can influence weight, including maternal health, dietary habits during pregnancy, and genetics. A mother’s proper nutrition and health care during pregnancy will positively impact the child’s development.
According to the “Reference Standards for the Growth and Development of Children Under 7 Years Old in China,” the normal weight range for baby boys is approximately 2.62 to 4.12 kg, while for baby girls, it is 2.57 to 4.04 kg.
While birth weight may be associated with brain and body development, the most critical factor is the care and nurturing provided by parents after birth.
Love, support, and a positive educational environment will contribute to a child’s overall well-being and intelligence. Therefore, in addition to focusing on weight, timing, and birth method, parents should also strive to create a solid foundation for their child’s holistic development.
