When a koala is first born, it is about the size of a jellybean and weighs around half a gram. Koala babies, which are called joeys (not 'cubs'), measure just 19 mm on average.
They grow quite quickly though and remain in their mother's pouch until about 22 to 24 weeks old. At the age of seven weeks they will have grown to about 26 mm and by 13 weeks their body weight will have increased to about 50 grams. At about 22 weeks old the joey will open its eyes for the first time and is able to poke its head out of the pouch and by 30 weeks old it will weigh half a kilo and will spent most of their time outside the pouch, clinging to the mother's stomach. By 36 weeks the joey will weigh about 1 kg (35 ounces) and no longer need to enter the pouch, although they will return to the mother's belly in cold, wet weather. At this stage, and until it leaves its mother in the next breeding season, it remain clinging firmly to the mother's back.
