And Chaos, I have just looked on Amazon and ebay for white noise machines and am inundated with the different options. Could you tell me which one you have.
This is the one we have but I'm not sure if they ship to the UK:

A lot of them have timers that switch it off after 60 mins, this one above is unlimited and we leave it on all night and at her nap times.
