Conchita is a white-naped mangabey, an endangered primate at the London Zoo. Her mother was seriously ill when Conchita was delivered via C-section, so zookeepers put a teddy bear into the newborn's enclosure. Now Conchita sorta thinks the bear is her mom. "She hugs that bear day and night," says keeper Andrea Payne. "She will run to the bear when she's alarmed. She won't run to me. She clamps on to it just like she would her mother." The teddy bear is "smelly" and has some monkey poo on it, but the zookeepers can't wash it. "To the baby it is her own special smell... The baby recognises the smell, it's a comfort to her. Washing the teddy would make it unrecognizable." [Times of London]
Poor baby monkey :(
And the monkey is NOT stupid; this is a lesson that bonding with a parental figure is hardwired.
This is why it's so hard to grow up and see your parents as "just" people and not want their approval/love/etc — even for those people whose parents are kind of rotten.
