What are the best ways to soothe a colicky baby?

First make sure that: nothing physical is wrong:hunger,dirty diaper,gas,pain elsewhere.If it's not, try swaddling, try white noise(record a vacuum cleaner running, ocean waves, other soothing noises),soft music,holding,rocking. Unfortunately, the same solution doesn't work for every baby,but just remember,colic isn't forever.Babies can sense your stress.Sometimes you just have to walk out of the room for a few minutes.
