In the world of infant health, colic is a four-letter word. Known to make otherwise healthy babies scream and cry uncontrollably for long periods of time, colic has no known cause. Luckily, when it comes to comforting a colicky baby, the best help is often homemade. Keep colic at bay by using what most of us already have around the house.

Rocking chair  Because gas is believed to be one of colic's chief culprits, gentle rocking can help babies not only calm down but pass gas. If you don't have a rocking chair, try an infant swing if your baby is at least 3 weeks old.

Vacuum  White noise can distract baby from his discomfort. Instead of buying a sound machine, turn on the vacuum cleaner, dishwasher or washing machine.

Towel  When placed on the abdomen, a warm towel can assist gas movement and reduce heartburn.

Car  A ride in the car can do wonders for colicky babies. But gas isn't getting any cheaper. For a more fuel-efficient alternative, try an infant seat with low-intensity vibration.
