Watch how patient this monkey is with his annoying baby sister

Davie the capuchin monkey loves his annoying baby sister Daisy. She can do no wrong in his eyes. He is so patient with her. He lets her climb on him, pull his fur, chew on his nose, and nibble his toes. He just sits there and lets her. Davie is four years old and Little Miss Daisy is only two months old but they have already formed a deep bond.
