How Do Kangaroos Carry Their Babies

Baby kangaroos, known as joeys, are born underdeveloped and rely on their mother’s pouch for safety and nourishment. This fascinating journey begins with their birth and ends with their growth and development within the pouch

In this article, we will delve into the life of a baby kangaroo by examining the stages they go through, from their birth towards their development as an adult.

The Journey of a Baby Kangaroo: From Birth to Pouch

When it comes to the birth of a baby kangaroo, the process is remarkably unique and swift. A mother kangaroo’s gestation period lasts for around 28 to 36 days, after which the joey is born in a highly underdeveloped state. The baby kangaroo’s journey from birth to the safety and nourishment of the mother’s pouch consists of several key steps:

Birth: After the gestation period, the joey is born weighing only about 1 gram and measuring around 2.5 centimeters in length. Its underdeveloped legs, body, and eyes make it look more like an embryo than a fully-formed kangaroo.

Crawling: Despite its fragile state, the newborn joey has developed forelimbs. These enable it to crawl up its mother’s fur toward the pouch by itself. This incredible crawl only takes around 3 to 5 minutes.

Entering the Pouch: The mother’s pouch is specially designed to protect and nurture the joey. Upon reaching the pouch, the baby kangaroo latches onto one of the four teats, which then swell to keep the joey attached for several months.

Once inside the pouch, the joey finds safety and nourishment, where it will continue to grow and develop into a healthy young kangaroo.

Life Inside the Pouch: Growth and Development

After successfully reaching the mother’s pouch, the baby kangaroo embarks on a new phase of its life, marked by significant growth and development. The pouch acts as the joey’s secure and nurturing environment, providing everything it needs for proper maturation. Key aspects of life inside the pouch include:

Feeding: Inside the pouch, the joey remains attached to one of the mother’s teats, constantly consuming nutrient-rich milk. The composition of the milk changes as the joey grows, ensuring it receives the necessary nutrients for proper development.

Physical Growth: Over the course of the next few months, the baby kangaroo starts to develop its legs, body, and eyes. This growth is gradual, yet impressive, with the joey increasing in weight and size until it becomes strong enough to emerge from the pouch.

First Few Hops: The joey will first peek out of the pouch around 4 to 5 months of age but quickly return to its safe haven. As it grows more confident, the joey will begin to spend more time outside the pouch, hopping around and grazing on grass while maintaining proximity to its mother.

Gradual Independence: Joeys usually leave the pouch completely by the time they reach 7 to 12 months of age, depending on the species, marking their transition to more independent young kangaroos. Mothers may continue to nurse their young for some time, even as the next generation starts to develop in the pouch.

The pouch plays a crucial role in a baby kangaroo’s early life, ensuring it receives the safety, nourishment, and warmth required for its growth and development.


The journey of a baby kangaroo from birth to adulthood is a remarkable and unique one. Born highly underdeveloped, the joey crawls up its mother’s fur to reach the safety and nourishment of the pouch. Once inside, the joey continues to grow and develop, consuming nutrient-rich milk and gradually increasing in size until it becomes strong enough to emerge from the pouch. This gradual transition to independence marks the end of the lifecycle of a joey as it grows into a healthy and self-sufficient adult kangaroo. The essential elements required for the growth and development of a baby kangaroo are provided by the pouch, emphasizing its critical role in their early lives and underscoring the fascinating and remarkable nature of these animals.
