For a start, the kangaroo does not use "his" pouch for anything. Only the female kangaroo has a pouch. This pouch is not used to just "carry" the joey, but it acts as the womb does in placental mammals, protecting and nurturing the young joey while it is developing. It has no other function apart from this. It is not used to collect food or for any other purpose.

A kangaroo gives live birth to a underdeveloped baby. The baby crawls upwards and enters the kangaroo's pouch. Once the baby latches onto a nipple, the baby stays inside the pouch until big enough to leave, though will get back in if frightened or tired.
Kangaroos usually pouch their Joeys (baby). When a Kangaroo gives birth it puts its Joey in their pouch.
