Research: Hospital books

There are children's books for doctors and hospital visits. Here are two that i liked:

Reading through these books, i have found that the illness is never really serious, to keep the child reading from worrying. This is fine, in our case as the MRI scan doesn't involve any operations or bloody stuff, just lying down.The ending in the books are always reassuring and happy. I think that this is something that we need to replicate for the client project, especially as the end needs to leave the child feeling good.
