Can I ask what your preferred technology is? There is so much for free on YouTube but the problem is that my laptop fan will come on periodically, and I don't really need the whole 8hrs a lot of those sleeping sounds programmes run.
Another option is to put some programmes on the iPod, but again, there is no timer option.
Trying to avoid cds and suchlike, also don't like earbuds, but happy to use speakers.
I bought a cheap white noise machine which is fine, small and very economical on rechargeable batteries, but I'd quite like a bit more variety of sounds (and my current choice - ocean noises - sounds kind of synthetic, so I think I could do better). This is the one I have now: amazon.co.uk/Mybaby-HoMedic...
Recommendations appreciated. TIA.
