Aunt Barby’s Invisible, Endless Owie by Tim Ingle and Barby Ingle Sometimes, explaining chronic pain to children is difficult, especially when the cause of the pain isn’t clearly visible. This hardcover book helps kids understand that people with chronic pain conditions often need special care, but that doesn’t mean they don’t like to have a good time. It talks about ‘Aunt Barby’ coming for a visit and how to get the house ready for a special kind of guest.
