These observations have sparked interest among researchers and psychologists alike, as children’s cognitive development plays a pivotal role in shaping their future.
To address these questions, experts have conducted extensive research and surveys to elucidate 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 linked to their birth method. Instead, a child’s cognitive development relies on multiple factors such as maternal health during pregnancy, genetic predispositions, nutrition, educational environment, and other variables.
There are clear medical indications for when a C-section is necessary. For instance, if vaginal delivery poses a threat to the life of the mother or child, or in cases such as macrosomia, 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 could lead to unintended risks for both mother and child, causing more harm to the child’s health and body during their early years. Therefore, mothers should heed 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 indicates 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 birthing experiences and found that nighttime deliveries took approximately 40 minutes longer on average than daytime births.
Longer labor durations correlate with increased health risks for the mother. Compared to daytime births, nighttime deliveries showed a 26% higher likelihood of birth complications, impacting both maternal health and child safety.
A mother’s health status during childbirth is intimately linked to the time of day. Typically, mothers giving birth during the day benefit from optimal medical support due to the full availability of healthcare staff.
In contrast, at night, many healthcare personnel from various departments have finished their shifts, leaving only a skeletal staff on duty. This reduction in medical resources can hinder efficient healthcare support, and in emergency situations, performing thorough checks on the mother and child in a timely manner becomes more challenging.

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, while a child’s birth weight does correlate with their IQ, 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 nutritional choices and health care during pregnancy will positively impact her 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 correlate with brain and body development, it is not the sole factor.
Infants weighing less than 2.5 kg at birth are typically considered premature and may require incubation for careful health monitoring. Conversely, infants weighing over 5 kg are considered macrosomic and may face health challenges or complications during their early care.
Although birth weight can influence brain and body development, the postnatal care and nurturing provided by parents are of utmost importance. Love, support, and a positive educational environment contribute to a child’s overall well-being and intelligence. Thus, beyond focusing on birth weight, timing, and method, parents should strive to create a solid foundation for their child’s holistic development.
