An Italian woman has become the country's oldest new mother at the age of 63, after giving birth to a healthy baby boy following fertility treatment in Ukraine.

Following months of IVF treatment in Ukraine, even under the threat of bombings from Russian forces, little Sebastian was born on June 3 to his mother Flavia Alvaro, according to the Daily Mail.

Flavia, who will turn 64 in October, gave birth to the baby, named Sebastian, who weighed nearly two kilograms (4.4 lbs), at Versilia Hospital in Lido di Camaiore, northwestern Italy, via a Caesarean section earlier than expected, with the pregnancy reaching 31 weeks and four days.

Flavia's fertility doctor, Andrea Marsili, told Corriere della Sera that Flavia did not inform him about her trips to war-torn Ukraine, where there is no legal upper age limit for fertility treatments, until she returned.

"She arranged everything independently and I was only informed afterward," he said about the new mother, whom he also described as 'a stubborn woman.'

Sebastian is currently in the neonatal intensive care unit and will be allowed to go home once he reaches a healthy weight.

However, his journey to birth was anything but easy. When Flavia arrived in Kyiv last fall, Vladimir Putin's forces were attacking the capital.

In the chaos of war, she ended up getting lost in Kyiv. The Ukrainian fertility clinic had to call her hospital in Italy to inquire about her whereabouts.

On top of having to undergo fertility treatment in Ukraine during a time when war was ravaging the nation, Flavia's treatment alone cost €15,000.

Flavia also suffered a miscarriage the first time she tried the treatment.

The record for Italy's oldest new mother was previously held by Italian singer Gianna Nannini for only 14 years, after she gave birth to her daughter Penelope at the age of 56.

However, Flavia is still not close in age to the current record holder, Indian woman Erramatti Mangamma, who gave birth to twin girls at the age of 73 in 2019.
