This video from 2011 went viral a year ago, and is trending ago now after appearing on ArbroathUniqueDaily, DailyPicks, and SayOMG.  

Baby Sophia took her first trip to the zoo, held closely tight to her mother’s chest. Mom took her to see the orangutan exhibit, but it was one of the great orange apes who was interested in Sophia.

The orangutan seems have a mother’s instinct, as she apparently oohs and ahhs over the human babe, pressing her face against the glass to get a better look.
