weighs 28 kilograms (61 lbs 12 oz). 

BARRANQUILLA, COLOMBIA (AUGUST 28, 2008) RCN -
 Colombian doctors are trying to determine why an 11-month old baby
already weighs 28 kilogram (61 pounds 12 ounces), the average weight of an
8-year-old in that country. 
    The boy's mother Milena Orosco de Agudelo said his exponential growth
began when he was 60 days old.  
    Tests show the baby has an endocrine system problem.  
    "He had some tests done and the results show that he has a thyroid
malfunction," said Orosco. "Then, he had a carpogram test done and
that test shows that he has the bones of an 8 year old boy, but they have not
told me where that came from."
    Doctor David Dias of the Barranquilla Pediatric Hospital said the baby
was still undergoing testing. 
    "The baby will have tests done to see if he's obese or we're
dealing with hyperthyroidism," Dias said. 
    The normal weight for an 11-month old boy is between 6 and 7 kilos (13
lbs 4 oz to 15 lbs 7 oz). 
    Because of his weight, the boy cannot wear his older brother's former
clothes and is limited to wearing large diapers.
