A sea of yellow t-shirts, hats, coats and cardigans was seen when schools took part in a day to raise awareness of childhood liver disease.

Pupils from both Park Hill infants and junior schools took part in Big Yellow Friday after Isha Khan’s mother Iram asked the teachers if they could do it.

The four-year-old was born with the debilitating liver disease bilary atresia, which can prove fatal if untreated.

And at two years old had a crucial liver transplant at Kings College Hospital.

Mrs Khan said last Friday’s activities at the schools in Stanhope Road, Croydon, not only helped raise more than £1,000 for the Children’s Liver Disease Foundation but also taught the children about Isha’s illness.

She said: “They now see that there is a child in their school that has had such a big operation and the other children now know that they have to protect her.

“Thank you to the schools for being so incredibly supportive.

“It was so much fun.”

And Isha’s teacher Bronwen Botes said: “It was incredible and everybody got on board.

“It’s definitely something we will do again.”
