White-fronted capuchins are polygamous.
The male mounts the female, holding her legs with his hind feet, and copulates with her for a few minutes.
Although the time of gestation is unknown, it is probably around 160 days like the tufted capuchin.
Usually one infant is born.
Observations of a newborn in El Tuparro National Park showed the process by which the newborn discovered the appropriate position for riding on the mother.
Newborns ride oriented sideways over the mothers' shoulders, but during the first days the baby holds on to any part of the mother such as the base of the tail, the tail, the legs, and the arms before discovering and learning that the position over the shoulders is best and most secure.
After several weeks the baby makes the change from the sideways position over the shoulders to riding on her back.

All the members of the troop are interested in the newborn, and they take advantage of any opportunity to examine and look at its genitals if the mother permits it.
With time the baby begins to climb up on other members of the troop, including the adult males who are interested in protecting the little one.
Playing behavior is principally with a companion, and all members of the troop from the alpha male, the mother and all young members of the group solicit play with the young one.
