It’s a big day for little Hayden Foulon.
The five-year-old London girl, whose father is a Wallaceburg-native, will be undergoing a stem cell transplant at Sick Kids Hospital in Toronto.
Hayden has been battling leukemia since she was just 22 months old.
To make today’s procedure even more special – Hayden’s donor is her 11 month old sister Harlow.
The family announced on Facebook this morning that they got the news back in December that Harlow is a perfect match for Hayden.
The odds that siblings are a stem cell match is just one in four.
