My father-in-law was diagnosed with Parkinson’s disease nearly 10 years ago. His tremor is noticeable and my daughter has known there is something that makes her Papa’s hands shake. For years, my wife and I chose to leave it at that because no other symptoms have been apparent to her, and she has not asked.

When kids turn a simple trip to the bathroom into a marathon session, the question shouldn’t just be “What are they doing in there?” but “What aren’t they doing?”
