Female chimpanzees give birth to a single infant (twins are rare) every 5 to 6 years. A newborn chimpanzee weighs 3–4 pounds and is born helpless. Within a few days it is able to travel by clinging to its mother’s stomach and by 5 to 7 months old it is strong enough to ride on her back.
Baby Bonobo (The bonobo is one of the most rare and intelligent animals in the world. They are a similar size to a chimpanzee, but bonobos are more slender and have smaller heads and smaller ears). Bonobos are found in the Democratic Republic of Congo, Africa.
