'World's heaviest baby': 11-month-old wears clothes meant for 3-YEAR-OLDS

A mum says strangers are left gobsmacked when they see her baby boy - who already wears clothes meant for three-year-olds.

Alexa Priego, 31, gave birth to baby Kason 11 months ago - but his size often fools people.

Her youngest son was born at a normal weight of 7lb 14oz but, after two months of breastfeeding, he became huge - and just kept growing.

Alexa, a mum-of-three from Manhattan, New York, said people often stop her in the street because they're stunned by his size.

Now 11 months old, he weighs the same as a two-year-old and fits in clothing for three year olds.

Alexa, a hospital administrator, said: "He is the heaviest baby in the whole world.

"He's very tall and very chunky - doctors said he is in the 99th percentile for weight and height.

"When people see him they ask his age, and they are shocked when I say 11 months because they expect him to be older.

"People are so amazed by it - but when my daughter was born, she was exactly the same.

"I guess I just make big babies!"
