Brunling reproduction takes place via aesexual internal fertilization, though developments in the area of assisted reproductive technology do exist. Brunlings are particularly notable for the fact that the ostensibly "male" members of the population—the apexes—are the child-bearers within the species. The average gestation cycle for brunlings is 32 weeks, with some varying by 28–30 days. Much like humans, brunling pregnancies are divided into development stages, with the embryonic stage taking approximately 4 weeks to complete. The following 8 weeks mark the fetal stage of the pregnancy. Brunlings develop faster than humans to compensate for the smaller share of childbearing individuals in the population. Thus, by 12 weeks, brunlings may induce an early delivery in necessary for the health of the father or for other medical reasons. Brunling infants are generally 5–6 kg (11–13 lbs) in weight and 48-56 cm (19-22 in) in height at birth. The larger body mass of a brunling apex compared to a human female is believed to contribute to the greater size of the infant's body during childbirth.
Compared to humans, the entire process of childbirth is remarkably safe. Complications and health risks historically associated with the birth are very low, and have been for centuries. As apexes give birth via flexible navel openings rather than the cramped and narrow birth canals in humans, childbirth for an apex is generally straightforward and painless, with a very limited labor process associated with it. The navel opening itself is blocked by a thick strap of stem cells and fat molecules known as the lorum, which is located between the navel opening and the canubula where the infant is located. Roughly one week before the child is to be born, the lorum will begin to degrade and liquify until access to the canubula becomes available. Once access to the canubula opens, the child can be retrieved, during which time they will be pulled through and coated in the remains of the lorum, the cells of which help boost the immune system of the child and shield them from a number of diseases and viruses already exposed to the father before and during pregnancy.
Childrearing among the brunlings is a process handled at different sexes during different stages of development. The task of nursing is traditionally the duty of mesas, or delegated to nadirs with developed mammary glands, while teaching has historically been the preserve of the apexes and mesas. Like humans, brunling children are helpless at birth for the first few years of their life. The brunling lifespan is divided into various stages of life, with five stages being the commonly accepted number of stages. The accepted stages are infancy, childhood, adolescence, adulthood, and old age. These stages are generally understood to have fixed periods, though generally typified by a rapid growth spurt during adolescence, and the rapid onset of senescence during the last 10-15 years of life. Apexes lose fertility around the age of 80. This process is very rapid, taking place in the last year of fertility, with the reproductive cycle of an apex shutting down permanently. It is believed this process prevents overpopulation as an apexes odds of siring apex offspring increases late in life.
The lifespan of brunling individuals varies greatly based on sex, genetics, lifestyle choices, and location of birth and upbringing. For primarily biological reasons, apexes outlive both mesas and nadirs by an average of 20 years. As of 2022, the life expectancy at birth for an apex was estimated to be 108.6 years, compared to 96.2 years for nadirs and 91.3 years for mesas. Within the less-developed regions of the brunling world, the median age is much lower due to higher mortality rates. As a species, there were approximately 480,000 centenarians (brunlings 100 years or older) worldwide in 2020.
