In 2012, Angela Formosa wasn't sure she would see her daughters survive their infancy. So it's incredibly special that Rosie and Ruby, both now 4, are ready to start their first day of kindergarten in September.
The twins were born conjoined at 34 weeks and delivered through C-section at the University College Hospital in London. They were joined at the abdomen and shared part of their intestine and had only a 20 percent chance of survival.
Rosie and Ruby then had emergency surgery just a few hours after being born because of an intestinal blockage.
