Raised by keepers since birth in December, experts at the San Francisco Zoo decided to introduce baby Hasani to his new surrogate mom, Bawang, yesterday. After a few cautious hours, the two got along wonderfully as you can see in this touching video. 

Surrogate gorilla mom Bawang has raised three offspring of her own and has proven to be a outstanding mother. Keepers noted that Bawang's handling of Hasani was very gentle and clearly demonstrated her natural maternal instincts kicking in.
