Jane Phillips, the hospital's interim head of nursing for children and young people, said: “We have tried getting more (fans) but they are out of stock everywhere we have looked. If anyone has any new fans they can donate, loan or sell to us we would be extremely grateful.
“We have some fans on the ward, and parents have brought in hand fans, but it’s not enough to keep the children comfortable.”
If you can help, please call Ward M on 01792 618891.
