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.

Are C-section babies or vaginally delivered babies smarter?
From a brain development perspective, a child’s intelligence is not directly linked to their birth method. Instead, a child’s cognitive development is influenced by various factors such as the mother’s health during pregnancy, genetic predispositions, nutrition, educational environment, and more.
There are clear medical indications for when a C-section is necessary. For instance, if vaginal delivery poses a risk to the life of the mother or the baby, or in cases of fetal macrosomia, abnormal fetal position, pre-eclampsia, 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 health and development 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?
Research suggests that there are notable differences between babies born during the day and those born at night. The American College of Obstetricians and Gynecologists conducted a survey of 429 women’s childbirth experiences and found that the average duration of labor for night births was approximately 40 minutes longer than for day births.
Longer labor durations increase health risks for mothers. Compared to day births, night births showed a 26% higher risk of childbirth complications, impacting both maternal health and child safety.
A mother’s health status during labor is closely linked to the time of day. During the day, mothers tend to be in better health due to optimal support from medical staff.
In contrast, at night, many healthcare personnel from different departments have finished their shifts, leaving only a small number 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 becomes more challenging.
Research indicates notable differences between day and night births.
Does a child’s birth weight reflect their IQ?
Aside from birth method and timing, birth weight is another significant concern for many parents.
In reality, a child’s birth weight does correlate to a certain extent with their IQ, but it is not the sole determinant of cognitive development.
Several factors can influence birth 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, it is not the only factor that matters.
Infants with a birth weight below 2.5 kg are typically considered premature and may require incubation for close monitoring and health care. Conversely, infants weighing over 5 kg are considered macrosomic and may face health issues or complications during their care.
Although birth weight can impact brain and body development, what matters most 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 birth weight, timing, and method, parents should strive to build a solid foundation for their child’s holistic development.
