I had Buggly Bear's Hiccup Cure by True Kelley as a child, and my parents brought it to us when they last visited. I sat down and read it to Charlotte during one of the few times she wasn't demanding a book written by Julia Donaldson and/or illustrated by Axel Scheffler. I honestly wasn't sure she was enjoying the book at the time, but ever since reading it she'll randomly come up to us and say "Hic!" like Buggly Bear does. I guess it made an impression on her. Kieran won't let us try any of the hiccup cures on him, though.
