After watching this video, I almost wished humans gave birth the same painless way as kangaroos. And in case you think that only kangaroo babies live in their mother's pouches during infancy, you may be surprised to know that kangaroos are just one of a species of mammals called "marsupials" that carry their young in pouches through early infancy. Koalas, oppossums and the tasmanian devils are all examples of marsupial mammals that carry their young in distinctive pouches.
Many parents can testify that babies who are carried in a soft pouch carrier close to their bodies cry less, are more calm and content. They also seem to sleep more peacefully, nurse better, gain weight better and develop better. More about the benefits of a pouch which is often considered parenting's best kept secret can be found here!I guess we can now also add human beings as a evolved class of marsupial mammals?
