Caught on camera: Mom stunned when seven-week-old baby looks up at her and says "hello"

(WITI) -- A seven-week-old baby has taken the Internet by storm -- by simply saying "hello."

In a video posted to Facebook by Cool FM, a radio station in the United Kingdom, a mother in Northern Ireland is heard cooing and saying hello to her son Cillian. Throughout the video, it appears that Cillian is trying to mimic and respond to his mom, Toni McCann. At the end of the 23-second video, little Cillian looks up and says “hello.”
