DD was born in a very hot country where we had the fan on all night so right from the start has had white noise whilst sleeping. We spent a couple of week in rural UK over the summer and quiet nights freaked her out completley and we used a white noise cd quietly in the room to help her with this, with the aim to slowly decrease the sound level. We now live in a very busy city, lots of traffic can be heard from our house, beeping horns and car alarms etc and so I have continued using the white noise cd to drown out some of this noise. Is this ok, or a bad idea? Should I be weaning her off it, and if so, does any one have any experience of living in a noisy area and the noise not affecting naps and night time sleep? Thanks.
