What is the birth process of a kangaroo?

How is a joey born?
Marsupials give birth to a live but relatively undeveloped fetus called a joey. When the joey is born it crawls from inside the mother to the pouch.

How long is a kangaroo baby when it is born?
one inch long
Newborn joeys are just one inch long (2.5 centimeters) at birth, or about the size of a grape.

A newborn joey can’t suckle or swallow, so the kangaroo mom uses her muscles to pump milk down its throat.
