World smallest Boy Baby was sent to home from Tokyo hospital

The world smallest surviving boy baby weighing just 268 grams at birth was sent home after months in a Tokyo hospital, Keio University hospital said.

The doctors feared that his life was in danger. The boy was born through Caesarean-section last August after he failed to gain weight during the pregnancy.

Then the boy baby was in intensive care until his weight reached 3.2 kilograms and now he was discharged said Dr. Takeshi Arimitsu of the university's School of Medicine, Department of Paediatrics.

"I want people to know that babies can return home vigorous even if they are born small", said Dr. Takeshi Arimitsu.

"I am grateful that he has grown this big because honestly, I wasn't sure he could survive", the boy's mother told Reuters.

According to the Tiniest Babies registry managed by the University of Iowa, The previous world record was held by a boy born in Germany in 2009 weighing 274 grams.

While the world smallest girl was also born in Germany, weighing 252 grams.
