Ndume's sister, Ibu, gave birth to a female infant on September 13, 1997, at the Pittsburg Zoo. The infant is being raised by her mother in the 10-member group led by silverback Mimbo, who is the baby's father. Ibu herself was hand-raised for three years due to maternal neglect, so her ability to care for her own infant is significant.
