What do kangaroos do with their young?

Kangaroos are mammals and so they give birth to live young which are suckled on milk, but more specifically they are marsupials. Marsupials give birth to (in Kangaroos a single) under-developed young which crawl from the reproductive opening into a pouch (marsupium) on the mothers abdomen. Once in the pouch the young (called a joey) latches onto the teat, which in many species swells to fill the youngs mouth, where (in Kangaroos) it suckles continuously for around 190 days (depending on species). After this time the joey will start exiting the pouch for short periods of time while still feeding from the mother, at this time it will begin to transition onto solid food after, slowly weaning off the mothers milk. It will remain permenantly outside the pouch once it is around 8 months old and after around 11 months it will be completely weaned.
