A 10-month-old baby boy was hilariously befuddled after meeting his mother's twin sister for the first time.

Dainius Sileika uploaded a video to YouTube that shows his wife handing off their son, Felix, to her twin.

Felix looks up at his aunt and becomes confused, not understanding who this strange person who looks just like his mom is.

He stares at her intently as he tries to make sense of the baffling situation.

The hysterical video has already been viewed nearly 1.5 million times on YouTube.

Watch Felix's priceless reaction above.
