Little Bantainam Sunn, a boy of under three from the north-eastern Indian city of Shillong, has developed an unusual adult habit.

While his playmates hanker after chocolates, Bantainam prefers something a little more fiery - chilli peppers.

We often find him rummaging in shopping bags in the kitchen looking for chillis

For more than a year now he has snacked his way through 10 chillies a day with his meals without batting an eyelid, or shedding a tear.

Shillong's local variety of chilli, the Naga Jolokia, is thought to be the hottest in the world, and many adults are unable to stand the heat.

Bantainam, however, eats them by the handful.

His grandmother, Mrs Lilee Sunn, told the BBC that he acquired his unusual taste when his parents took him to a local restaurant.

"Bantainam just took three chillies from the table and munched them watched by his disbelieving parents,'' said Mrs Sunn.

She said despite all efforts to keep chillies away from him, he asks for them daily.

"Now, we have to keep a container full of chillies only for him."

Record-breaker?

Last year Japanese scientists said the Naga Jolokia was the world's fieriest chilli.

I don't like chillis at all, unlike my brother

They found it measured 855 Scoville units - nearly 50% hotter than its nearest rival, Mexico's Red Savina Habanero.

Bantainam's father, Augustine, said his son eats more chillies than chocolates or sweets, and still does not shed tears or show signs of any burning sensation inside his mouth.

He said he had taken his child to a local doctor who found him to be normal and healthy.

Bantainam's two older sisters have no interest in chillies at all, said Augustine, a caretaker at a Roman Catholic cemetery in Shillong.

Local community leaders are convinced the boy is one of a kind, and plan to ask the Guinness Book of World Records to send representatives to verify his singular habit.
