How long after a natural childbirth should one wait before having another child?

Generally, there is no absolute "best" time, but it is recommended to wait 18–24 months after a vaginal delivery before preparing for the next pregnancy. By this time, most mothers have sufficiently recovered physically and are better prepared for another pregnancy. If in doubt, it is advisable to consult a healthcare provider in advance. Detailed analysis is as follows:

If the mother is young and recovers quickly after childbirth, she may begin preparing for the next pregnancy around 18 months postpartum, provided medical evaluations confirm that her uterus, ovarian function, and overall physical condition have returned to pre-pregnancy levels. At this stage, bodily functions are generally stable, reducing the risk of pregnancy-related complications and allowing sufficient time to care for the previous child, thereby minimizing impact on family life.

If the mother is older (over 35 years) or has a slower postpartum recovery (e.g., anemia, poor pelvic floor muscle recovery), it is advisable to extend the interval to 24 months or longer. For older mothers, egg quality declines over time; a longer interval allows for more thorough physical recovery, reducing risks such as gestational hypertension and preterm birth, thus protecting maternal and infant health.

After a vaginal delivery, regular postnatal check-ups are necessary to assess physical recovery. Before attempting another pregnancy, a comprehensive medical evaluation is recommended to ensure the body is ready for conception. During preconception, attention should be paid to folic acid supplementation, maintaining regular sleep patterns, and balanced nutrition to optimize conditions for pregnancy.
