The smallest baby in the world was born at Keio Hospital in the summer of last year (2018) weighing only 268 gram!
If the mother had waited until the full term, the baby would have died in the womb because the baby wouldn't have received enough nourishment.
He was delivered by caesarian (section) at 24 weeks. He grew up little-by-little and has recently left hospital as a healthy baby able to feed normally.
Congratulations!
Do you know your birth weight and date and time of birth?
