Quck answer
Orangutans have the ability to nurse their young for up to 20% of their lives, which is longer than any other mammal. This extended nursing period allows for the development of strong bonds between mother and offspring, and can also provide the young with important nutrients and immunity. However, as orangutans face habitat loss and other threats, this unique nursing behavior may be at risk. Conservation efforts are crucial to ensure the survival of these intelligent and fascinating primates.

Feeding infants can be taxing after a year or so. Although humans have different cultural practices regarding nursing, it is uncommon for us to breastfeed children beyond three years old. Other primates, such as gorillas and chimpanzees, suckle their young for longer periods of time, but none compare to orangutans, who nurse for an impressive duration.
A study published in the journal Science Advances reveals that while previous research indicated that baby orangutans nurse for six to seven years, the maximum time is closer to eight or nine years. Orangutans, which are endangered and only found in the rainforests of Sumatra and Borneo, are difficult to observe because they are private animals and their babies breastfeed at night, hidden away in nests. Studying their nursing behavior is essential to understanding their reproductive cycles and the amount of maternal investment required to raise a baby orangutan successfully.
Teeth can provide significant information about animals. The researchers analyzed the barium in dental samples to determine how long wild baby orangutans typically nurse. Bone forms rings as teeth grow, akin to the layers in an Everlasting Gobstopper. Barium, a chemical element found in breast milk, is present in a ring of tooth skeletal tissue, indicating that an infant or young orangutan nursed that year.
The researchers discovered that while barium levels in four individual orangutan babies decreased after the first year of life, the element could be detected through their eighth or ninth year. Barium levels were higher during some parts of the year, suggesting that the young orangutans consume fruit when it is available. During times of fruit scarcity, they often return to nursing to supplement their diets.

FAQ
1. What is the lifespan of an orangutan?
Orangutans have a lifespan of around 35-45 years in the wild and up to 60 years in captivity. They are among the most intelligent primates and have a slow reproductive rate, with females giving birth to only one offspring every 6-8 years.
2. At what age do orangutans start nursing?
Orangutans start nursing soon after birth and continue for up to 6-7 years. The first few months are critical for the baby orangutan as they rely solely on their mother’s milk for survival. As the baby grows older, they start to explore their surroundings and learn how to climb trees, but they still nurse for several years.
3. How much milk does an orangutan produce?
An orangutan mother produces around 1 liter of milk per day, which is rich in nutrients and antibodies. The milk is essential for the baby’s growth and development, and it also helps to build a strong bond between the mother and baby.
4. Why do orangutans nurse for so long?
Orangutans have a slow reproductive rate, and their offspring require a lot of nurturing to survive in the wild. Nursing for an extended period allows the mother to pass on important survival skills to her offspring, such as how to find food and avoid predators. It also helps to ensure the baby’s immune system is strong enough to fight off diseases.
5. How do orangutans wean off nursing?
As the baby orangutan grows older, they start to eat solid food and rely less on their mother’s milk. The weaning process can take several years, and it is a gradual transition. The mother will start to spend more time away from the baby, encouraging them to become more independent. Eventually, the baby will stop nursing altogether and become fully independent.
