Siamang gestation period is between 6.2 and 7.9 months; after the infant is born, the mother takes care of the infant for the first year of its life.[10] Siamang males tend to offer more paternal care than do other members of the family Hylobatidae, taking up a major role in carrying an infant after it is about 8 months old.[2] The infant typically returns to its mother to sleep and nurse. The infant begins to travel independently from its parents by its third year of life.[3]
