Both Henry Connolly and his friend Alex Xenias were treated for heart problems as babies, and Henry’s mother Lucinda wanted to organize support for the 10th anniversary of Wear Red Day.
She said the family, who live in Harrogate, were overwhelmed with the day’s support.
Lucinda said: “”I have been so touched by the generosity of our entire school community, it is so important to support these small charities, especially on these dedicated awareness days, they only come once a year.
“No matter how much each person gives, every little bit counts.
“No one knows when any of us might need help from the charity for our own family.
“I’m glad the school took this on board, it really helped raise awareness and raise more urgent funds for this important charity.”
Lisa Williams, of the Children’s Heart Surgery Fund, said: “We were delighted to see Highfield Prep School celebrate ten years of Wear Red Day – an event that holds such significance for our charity and our supporters.
“Local schools, businesses, community groups and individuals came out in force this year to raise valuable funds for the Children’s Heart Surgery Fund and raise awareness about congenital heart disease.
“A big thank you to Highfield Prep School for helping us continue our vital cause to support Hearts for Life in our area.”
Ms Sylvia Brett, Principal of Harrogate Ladies’ College and Highfield Prep, said Highfield’s parents had once again shown their commitment to charity.
She said: “I am so proud of how our parents step up and support charity events and place such a high value on fundraising in our community.
“It was a great and wonderful day to see the kids supporting each other.”
