Marsupials essentially give birth to fetus (hind legs not yet developed, for instance), which then migrate to the placental pouch, where they attach to a teat and where they complete their growth.
Placentals mammals have an extra organ, the placenta, that provides an interface between the mother and child circulatory systems until birth.

marsupials complete development in a pouch and placentals complete development in a placenta.

marsupials complete development within the body and placentals complete development in a placenta.
marsupials complete development in a pouch and placentals complete development in a placenta.
marsupials nourish their young with milk.
are your options.
