Kiki came right up to the glass, her attention fixed on the baby. She stared at him lovingly and curiously. She touched the glass, as if trying to touch the baby’s hand or pet his face. The adorable moment got the attention of fellow zoo visitors. “It was so sweet,” Emmily said. “For like well over five minutes she just sat there watching him and just staring at him so lovingly.”

It was as if there was a spiritual bond between the two new mothers: it turns out that Kiki, a mother of five, had given birth to her youngest son, Pablo, in October.

And as Emmily showed her baby, Kiki decided to bring Pablo over and show off her own child.

Needless to say, it was an unforgettable trip to the zoo for this mother and baby, giving them a beautiful moment to remember forever. Their story went viral just in time for Mother’s Day this past Sunday, a touching reminder that a mother’s love transcends species. “We had so many people stop us and tell us that was the most beautiful thing we’ve ever watched,” Emmily told News Center Maine. “And it was so touching, it really was. You could feel the emotions were just in the air.”
