One of my boys used to get terrible colic as a babe and this is what we did (as advised by ..... I can't remember now)
Anyway, lay the babe face down on your forearm, bum towards your elbow and your hand palm upwards supporting head and upper chest. The babes arms and legs should hang down so the babe is sort of draped along your arm. Optional gentle rubbing of back and soothing noises may be made.
For us it worked almost instantly, at the very least it's worth a try as it can do no harm.
BTW, I always performed this duty as my arm/hands are much larger than OHs
Do not believe anything until it has been officially denied
