Eastern pygmy possums typically breed twice a year, although they may breed a third time if food is plentiful. Females have a well-developed pouch with four to six teats, and usually give birth to four young, although larger litters are not uncommon. Gestation lasts around 30 days, after which the young spend 33 to 37 days sheltering in the pouch.
