A Chatham woman has given birth to the rarest set of twins.
Kaley Johnston-Wilson gave birth to a pair of "mono-mono" girls on July 23 at a hospital in London. Mono mono twins, or monoamniotic-monochorionic twins, are identical twins who share a single placenta and a single amniotic sac. According to Hamilton Health Sciences, they happen in about 1 in 10,000 pregnancies when one fertilized egg splits very late.
Johnson-Wilson told CK News Today the girls were born at 33.4 weeks and are currently in the Neonatal Intensive Care Unit in London.
Mom said the twins are doing very well and should be transferred to the Chatham hospital in a couple of weeks when a bed becomes available.
Johnston-Wilson added that she found out she was having twins during the first ultrasound, but didn't know they were mono-mono twins until week 12.
"I had some hesitation because I did some research and I was scared of the worst-case scenario. But after a while, and my nerves were calmed, I was actually very excited for the outcome of twins," said Johnston-Wilson.
She said she was monitored for a couple of months because this type of pregnancy is high-risk and had to have a C-section (cesarean section).
"Every mono-mono case does result in a C-section because of the high risk of cord entanglement and blood-to-blood transfusion of the other twin stealing the blood," she added.
Johnson-Wilson added that there are no special plans for welcoming the girls home. She's just hoping that the homecoming goes smoothly.
