We usually have a parenting book or two in the bathroom for browsing. Sure, sometimes I flip through looking for answers. But the real reason I like having them to hand is to read sections on challenges that we don't face. My personal favourite is reading about bedtime battles. Our house shuts down at 7:30, and reading about the horrors we could be facing gives me a smug glow that lasts at least 2 minutes. The trick then is to close the book.
I'm thinking that this could extend beyond parenting. Perhaps I should read books about anxiety (not depression), eating disorders (not garden variety over-eating), and post-traumatic stress! This could be fun.
