The reproductive habits of the pygmy slow loris are very similar to those of the slow loris. Mothers give birth every 12 to 18 months, producing small litters of one or two individuals after a 188-day gestational period. When first born, infants cling to their mothers' bellies, but mother's will "park" their infants on a suitable branch (or in captivity the side of a cage) from day one whenever they need to forage for food. Infants are soon capable of moving around short distances on branches after being parked. Infants are weaned at about 133 days. Female offspring reach sexual maturity first, usually around nine months of age, while males may not do so until 18 or 20 months have elapsed.
