Ollie is due for his first appointment at Stanford Children’s Hospital on 8 January and it will be one of 10 before he is taken in for surgery.
Jasmin said: “I’m, very nervous I’m very scared, but I think right now I’m ready to be there with him, in California.”
How long Ollie takes to recover will depend on how he responds to the surgery, but Jasmin said they expected to remain in Califiornia for between two and three months, before he is able to fly home.
By the end of the year, Jasmin said she hoped the second stage of the procedure could be carried out in the UK and by 2027 a full repair would have been carried out.
“I’m just hoping that by next year we’ll be in a very different place,” she said.
