Kirsty Hannam and her partner Rob O'Hara with the two sets of twins, William and Willow and Alice and Aoife. See SWNS story SWFTtwins. A woman told she'd never have kids is delighted after she gave birth to FOUR babies in just over one year. Kirsty Hannam, 31, was diagnosed with endometriosis at the age of 18 and doctors told her it was very unlikely she would be able to have children of her own. But in November 2018, just three months into their relationship, Kirsty and her partner, Rob O'Hara, 34, a civil enforcement officer, found out they were expecting twins. Kirsty was overjoyed to give birth to William, who weighed 5lbs 9oz, and Willow, who weighed 6lbs 7oz, on the 11th June 2019 at Bath Royal United Hospital with Rob by her side. But just six months later Kirsty was admitted to Royal United Hospital, Bath, with severe pain caused by her endometriosis. Doctors told her she would eventually need a hysterectomy in order to alleviate intolerable symptoms of the disease - but chose to wait a little longer, just in case. Kirsty was stunned to find out she was pregnant with twins in March 2020 - just seven months after the birth of her first set. Kirsty gave birth to twin girls, Alice, who weighed 5lb 6oz, and Aoife, who weighed 5lbs 3oz, on October 14h 2020 at Bath Royal United Hospital - defying the odds by 12,500 to one.
