Taking the baby for an outing in a baby carriage or stroller may also help. White noise, an electronic noise with a constant intensity, is also very effective even a dishwasher or vacuum cleaner can lull the baby to sleep. Try combining motion and white noise by carrying the baby in a pack while you're vacuuming. One father while holding his crying baby, found that the noise of the aerator on a nearby fish tank soothed the baby. Some parents find their child sleeps better with the noise of a ticking clock-perhaps because it simulates the sound of the beating heart heard in the womb.
Some companies market audiotapes of white noise chat have been shown to help.
A favourite trick of experienced parents is to take the baby for a ride in the car. This combines movement with the white noise of the engine and the air rushing past and it works in some cases. Just don't he surprised if the baby wakes up as soon as the car stops. Some companies have capital-ized on this idea by selling devices that attach to the crib, imitating the motion of a car. Sometimes wrapping the baby snugly in a blanket can help.
