Hiccups are strange gulping sounds caused by involuntary sudden contractions (spasms) of the diaphragm. The diaphragm is a dome-shaped muscle at the bottom of the chest.
Hiccups often accompany indigestion or an over-full stomach that presses against the diaphragm. A child may have hiccups after drinking too much carbonated beverage.
Give 1 teaspoon of dry granulated sugar to your child and have him swallow it quickly. If this doesn't work the first time, repeat it 3 times at 2-minute intervals. For younger children use corn syrup. Babies can be given a swallow of water. The child should also lie down. If this doesn't work, gag your child 3 or 4 times by pushing down on the back of the tongue with the handle of a spoon.
Other children are helped by rubbing the uvula or soft palate with a cotton swab, or by pulling the tongue outward with the fingers.
Call IMMEDIATELY if:
The hiccups last more than 3 hours (the usual time needed to empty the stomach) and your child is uncomfortable.
