The difference you make

Wallace & Gromit’s BIG Christmas Dress Up is loads of fun – but it’s always nice to know where your fundraising goes.

Over 100,000 children from Bristol and beyond are treated in Bristol Children’s Hospital every year. Meanwhile, hundreds of critically ill and premature babies are cared for in St Michael’s Neonatal Intensive Care Unit.

These children need your help – and with the funds you raise, we are able to provide vital services that otherwise wouldn’t exist: free family accommodation, music and play therapy, groundbreaking research, top-of-the-line equipment, staff uniforms, toys, presents for every child in hospital on Christmas day… and so much more.
