I am a card maker and was wondering about sending cards to the children. Esp. those children that have no family visiting. Who would I contact?

That is hard because you have to personally know who and who isn't getting a visitor. Because of so many kinds of people and privacy, you have to goto the hospital and get that type of permission from the patient and also the hospital in order to get a card to that individual(s).

I would say contact the hospital directly and ask
