At our hospitals, we have a number of volunteers called "Pink Ladies" - they wear pink shirts and provide all sorts of ancillary services to hospitals. If you have something similar, you could approach them at your children's hospital, or go to a children's charity. Perhaps your Education Authority could help out? Teachers go into hospitals to teach long - term sick kids here. Failing all of that, I would just approach the administration of your local children's hospital - you might be starting something. I have made quilts for a palliative care hospital in my area and just give them to the office.
