Getting Baby to sleep
Many people naturally assume that the best environment for sleep is one of total silence: most of us are familiar with having to tiptoe around a sleeping baby's room. Although a quiet environment is the best one for most adults, you'd be well advised to remember where your newborn baby has been sleeping for the past nine months: in his mother's womb. In the womb, of course, your newborn slept in many situations that were far from quiet - when the mother was out in public, or socializing with other people. For this reason it is easier getting baby to sleep by being exposed to some quiet background noise.
Quiet but not silent
You should be trying to allow some ambient "white noise" to be around your baby when he goes to sleep. Sudden loud noises will, of course, rouse him, but in most cases some background chatter and other soothing noises will help getting baby to sleep.Most adults, I'm sure, can likely remember falling asleep to the sounds of their parents and their friends having a conversation.There are products marketed to new parents to create these ambient noises - most notably audio CDs containing tracks of soothing noise. It usually isn't necessary to buy these, however - in most cases simply leaving the door to the baby's nursery ajar will do the trick of getting baby to sleep. In a similar vein, if your baby falls asleep around company, allow him to stay there rather than moving him to a quiet room.
By helping to create the best possible environment for your baby's sleep, you help him learn to get to asleep in his own. Often a humming noise can help - we all know how easy it can be to get baby to sleep in a moving car - so having a humidifier or fan in the baby's room can often do wonders.
Whatever solution you choose, remember that it needn't be overly complicated. Simply leave the door ajar, or let your baby sleep in the company of others. Contrary to what many people intuitively think, getting your baby to sleep in a little noise is better than total silence.
