Two caregivers take turns sleeping with Baraka, trying to mimic the care she would have gotten from her mother in the wild.
"Gorilla mothers are very attentive toward their babies," Eddy Kambale said. "The mothers feed them, sleep with them, carry them on their chest or back, groom and clean them, watch them, and protect them against predators, and even rain, at all times."
In the sanctuary, the orphans spend time outside in the forest yard, but mostly their caretakers carry them, as their mothers would. The caretakers use gorilla vocalizations to calm the infants.
"If no one will try to imitate their mothers' behaviors, the infant gorillas can shortly die from stress, as they are very fragile," Kambale said.
