What Is a Baby Kangaroo Called?
A baby kangaroo is called a joey. When it’s born, it’s tiny—about the size of a jellybean—and extremely fragile.
You’ll find the joey crawling into its mother’s pouch right after birth, where it latches onto a nipple and stays safe.
Inside the pouch, it grows fur, gains strength, and learns to control its body temperature before exploring outside.
This unique process helps the joey thrive in its early stages of life. Keep exploring to discover how this amazing journey unfolds for a baby kangaroo.

What Is a Joey? A Baby Kangaroo Explained

Although you might know kangaroos as iconic Australian animals, you may not realize that their babies, called joeys, start life incredibly tiny—about the size of a jellybean. When a baby kangaroo is born, it’s extremely underdeveloped, comparable to an 8- to 10-week-old human embryo.
Despite this, the joey immediately begins a vital journey. It crawls from the birth canal into its mother’s pouch, where it will continue to develop safely. Inside the pouch, the joey latches onto a nipple to nurse, getting the nourishment it needs to grow strong.
This pouch acts as a protective nursery, providing warmth and security as the joey gradually develops. For several months, the joey stays inside, growing steadily before it becomes ready to explore the outside world.
How Does a Joey Grow and Develop Inside Its Mother’s Pouch?

Once the tiny joey reaches its mother’s pouch, it continues to nurse and grow. It transforms from a fragile jellybean-sized newborn into a curious, active young kangaroo.
Inside the pouch, the joey finds a protected environment where it can safely grow and develop. Nursing is continuous because the mother’s muscles pump milk directly into the joey’s mouth.
Over time, the joey’s fur starts to grow, and its ability to regulate body temperature improves. This prepares it to mature outside the pouch.
The joey stays inside the pouch for 4 to 11 months, depending on the species. It gradually becomes more active and starts exploring beyond the pouch when it’s ready.
| Stage | Development Inside Pouch | Key Feature |
|---|---|---|
| Birth | Jellybean-sized, fragile | Nursing begins |
| Early pouch life | Fur starts growing | Protected environment |
| Mid development | Improved body temperature control | Increased activity |
| Late pouch life | More curious and active | Preparing to mature outside |
| Leaving the pouch | Independent young kangaroo | Exploration begins |
