Dr Robert C Hamilton says his technique, dubbed "The Hold", works every time without fail.
He picks up the child, folds his or her arms across the chest and holds this tight, lifting the baby's bottom with the other.
Holding the baby at a 45 degree angle with both hands, he then lifts the baby up and down, rocks it back and forth and "shakes the little booty".
"You hold the child with the fleshy part of your hand [the palm] not the fingertips, and I am supporting his chin, which is why I am holding him at a 45 degree angle."
"Everything you do is very gentle, you don't want to do any jerky motions ever," Dr Hamilton advices.
He adds that The Hold works best for babies up to three months as they then become too heavy.
