WOW! See The Smallest Baby Boy Ever To Be Born… weighing just 0.4kg (Photos)

The world’s smallest surviving baby ever has finally been allowed to return home after spending six months in hospital. The teeny newborn – who hasn’t yet been named – was born last August weighing 0.59lbs – less than a block of butter.

The cute boy was born via emergency c-section at the

Keio University Hospital in Tokyo after doctors noticed that he wasn’t growing during a 24-week scan. They decided to operate for fear that his life might be in danger.

The baby, who could fit into his doctors’ hands, was treated at a neonatal intensive care unit where medics got his weight up to 7.14lbs (3.2kg).

The Sun UK reports that last Wednesday, he finally left hospital – two months after his actual due date. The little boy was kept in hospital where his weight and breathing could be monitored, and where he eventually got the strength up to start breastfeeding.

The paediatricians who treated the baby are hoping that his incredible success story will give hope to parents whose children are born very prematurely or too small to go home immediately.
