Big baby !

CANCUN, Mexico -- His name is Antonio Vasconcelos, but they're calling him Super Tonio.

And he is an unusually big baby.

The not-so-little fellow weighed in at a whopping 14.5 pounds Monday when he was born in the Mexican resort of Cancun.

He became a sensation there, with people lining up outside the window of the nursery ward to get a glimpse.

He is 22 inches long and has been chowing down on 5 ounces of milk every three hours.

Antonio is still far off the big-baby record. That's held by a Italian born in 1955. He weighed 22 pounds, 8 ounces.
