A single offspring, weighing 30 to 50 g, is born once a year. For the first 2 weeks, the young are cared for solely by the female. The male takes over in the third week and the young return to the female only to nurse for 15 minutes at a time. After the fourth week, the entire group cares for the young.

Exploring and play are very important to the young, as this is how they learn essential survival skills. They are weaned after 65 days.

Sexual maturity: female 8.5 months, male 16.5 months. Gestation: 139 to 180 days (average: 155 days).
