zsl-edge-of-existence:Baby sun bears are born blind, hairless, and helpless, and are completely dependent on their mothers for their first three months. Their mothers will carry them in their mouths or, unusually, by cradling them in their arms while they walk on their hind legs, a behaviour seen in no other bear species. The cubs nurse from their mother for around 18 months, and will stay with her until they are two years old. Females are ready to find a mate of their own by the time they are three, and males reach sexual maturity at around four. -- source link
