I had a similar reaction to water when I was younger, and we never pursued medical care for it because it was relatively minor, just an annoyance. I'm sure there are many more like me.

My husband read the Hobbit to all of our kids, and LOTR to the older ones (now 11 and 9; our youngest is 6). It's been their "thing" and they loved it. He watched the movies with our oldest as they finished the books.

My own ritual with them has been reading the Harry Potter books; we've been discussing starting with the youngest soon.
