Have you ever wondered what's going on in a kangaroo's pouch? We went ahead and took a look inside.

A pouch is mostly hairless. Its warm skin helps keep babies alive, and nipples provide nourishment.

A joey can be born as small as a grain of rice or as big as a jellybean.

But he has the paw and forearm strength to drag himself to his mother's protective pouch!

A mama kangaroo is able to nurse joeys of different ages at once.

Each nipple is capable of producing milk with different nutritional content than the next!

In fact, a kangaroo can nurse up to three different joeys between 0 and 12 months old at once.

It allows an endless cycle where she can get pregnant again right after giving birth.

Since the joey stays in the womb for so long, it's up to the mother to clean her pouch once the baby does his business inside.

She pops her head inside and licks it clean. Clearly, this mom will do ANYTHING for her kid.

Once the baby is finally ready to venture into the world, he still needs milk.

No problem: He just pops his head back in the pouch for a sip every so often.

Either way, they do it more adorably than anyone else we can think of.
