Q: Why do newborns get hiccups so often?
A: Hiccups are caused when the diaphragm, the respiratory muscle at the base of the chest, gets irritated and spasms. Since a baby's stomach and torso are small, it doesn't take much to fill his tummy to the brim and push it up into the diaphragm. In fact, it's a good thing to see kids get hiccups -- it means they're well fed. --Hagar Scher
