Like other baboons, the hamadryas baboon breeds aseasonally.
The dominant male of a one-male unit does most of the mating, though other males may occasionally sneak in copulations, as well.
 Females do most of the parenting.
They nurse and groom the infant and one female in a unit may groom an infant that is not hers.
Like all baboons, hamadryas baboons are intrigued by infants and give much attention to them.
Dominant male baboons prevent other males from coming into close contact with their infants.
They also protect the young from predators.
The dominant male tolerates the young and will carry and play with them.
When a new male takes over a female, she develops sexual swellings which may be an adaptation that functions to prevent the new male from killing the offspring of the previous male.
When males reach puberty, they show a playful interest in young infants.
 They will kidnap the infants by luring them away from their harems and inviting them to ride on their backs.
This is more often done by "follower" males.
This kidnapping can lead to dehydration or starvation for the infant.
The harem leader would retrieve the infants from their kidnappers, which is mostly an act to protect their offspring.
