From Britian's The Guardian:
As the picture clearly shows, Antonio Vasconcelos - he's the one at the back - is no ordinary new-born baby.But it seems that that's not the largest, by a long shot. From Fox:
Dubbed "Super Tonio", he startled staff at the Jesus Kumate Rodriguez hospital in Cancun, Mexico, not to mention his mother, by arriving via caesarean section on Monday weighing a whopping 6.6kg (14lb 8oz), roughly twice the average weight for a newborn baby.
Crowds have gathered at the windows of the hospital's nursery ward to marvel at Antonio, who is already 56cm (22in) long and drinks prodigious amounts of milk.
In Brazil, a baby born in January 2005 in the city of Salvador weighed 16 pounds, 11 ounces at birth. According to Guinness World Records, the heaviest baby born to a healthy mother was a boy weighing 22 pounds, 8 ounces, born in Aversa, Italy in September 1955.Photograph: Elizabeth Ruiz/EPA
