Santiago Fandino isn't your average eight-month-old Colombian baby.

He weighs 44 pounds or 21 kilos, which is three times more than an average child of his age.

He currently weighs the same as a five-year-old toddler.

His mother noticed there was a serious problem when he couldn't move because of his weight.

Doctors say there is no medical reason for his obesity, he's simply been overfed.

They have taken him off formula milk and put him on an emergency diet of vegetables and juice.
