Hair dryers, vacum cleaners and washing machines are some of the more unusual sounds that can send a baby off to sleep.
A survey from Johnsons has revealed that a lack of sleep is the biggest challenge faced by Irish parents who will go to any lengths to get their babies to sleep.
The top three soothing sounds are a Mum or Dad's voice - a song or a lullaby.
But others find a hair dryer - vacum cleaner or washing machine can often get better results.
