My youngest daughter had hiccups twice this week. On Friday morning she asked, “what are hiccups?” Fortunately, I knew the answer. Unfortunately, I didn’t have a great way of explaining involuntary muscle contractions to a three-year-old. I did my best and told her that it’s part of her body’s way of growing and getting stronger (hey, you try explaining it to a toddler). If she was a little older, I might have turned to the TED-Ed lesson, Why Do We Hiccup?

Why Do We Hiccup? explains what causes hiccups and why hiccups are more common in children than in adults. The video also dives into attempt to explain why humans hiccup but other exclusively air-breathing animals don’t.
