I do not know if you’ve ever heard of it, but it is a fact that a vacuum cleaner is not only good for cleaning, but also has a calming effect on babies, so does the hairdryer which has a powerful impact on lulling the newborns to sleep. As a happy father I can confirm the calming effect of these sounds. It is mentioned in a many baby guidebooks and even midwives and pediatricians recommend it. Especially in the first few weeks and months of the newborns, the lack of the comforting and protective womb causes restlessness. The new feeling of having an endless unfamiliar space around them causes irritation and discomfort, hence leads to the search for cuddliness of the womb. Colic is also often a reason for restlessness. Monotonous everyday sounds remind babies of their time in the womb. The time before birth is a worry-free, secure, and safe time in which babies feel the protection of their mothers. The sound of a hairdryer, vacuum cleaner, or even a washing machine is similar to the sounds they hear in the womb. So they take restless babies back to this time and help them to calm down. The sounds on this CD are ideal for your iPod, CD player, and even for your car. This would also be the perfect gift for a baby shower. Energy efficient and always accessible, your sleepless nights will become a thing of the past.
