• It typically conceives a new embryo days before delivering the newborn from its previous pregnancy.

• Female wallabies have two uteri and two separate ovaries. At the end of a pregnancy in one uterus, a new embryo develops in the other uterus. Wallabies regularly have an embryo in the uterus, a young joey in the pouch, and a third semi-dependent young at foot, still drinking its mother’s milk.

• In the swamp wallaby (Wallabia bicolor), the new conception happens one or two days before the previous joey is delivered.
