Unlike most marsupials, the female numbat does not have a proper pouch. Instead, her abdomen and thighs swell when she is nursing, and she has a patch of long, crimped hair on her belly for her joeys to cling to.
The female numbat has one of the shortest pregnancies of any mammal, with her babies being born only two weeks after mating. She will give birth to up to four joeys, and they will cling to her nipples and suckle as she continues to wander and hunt. The young are born with short, stubby snouts to make nursing easier, and grow the long noses of adults after weaning. Weaning occurs after nine months, but after six they are too big for the female to carry, and will be left at the nest while their mother hunts.
