  5. Reproduction & Baby Chimpanzees Chimpanzees are fully grown and able to reproduce at 12-13 years old. Female chimpanzees are pregnant for about 8.5-9 months and usually have a single baby at a time; twins are rare. Female chimpanzees carefully nurture their young. Babies can grasp their mother's fur to ride on the mother's back at about 6 months. After they are weaned, chimpanzees begin to build their own sleeping nests out of vegetation and not use their mother's nest anymore. Young chimpanzees stay with their mother for about 7 years.
  6. Parental Care Majority is the responsibility of the mothers Critical to the survival and emotional health of youngsters Youngsters benefit from the close relationship with their mothers in terms of food, warmth, protection, and the opportunity to learn skills Social bond that the young have with their mother is remarkable Even after they are adults they will continue to have affection and caring for her. As the mother gets older the child will be at her side and do all they can to care for her.
