Has anyone got a good recommendation for a night light? I know its better not to have one but my autistic son won't sleep without a light of some sort on. I've looked at the one in GLTC which doesn't get hot and can be made brighter or dimmer and fade gradually all together. Its £19.99 + P&P so I just want to make sure I'm getting the best one I can find without having to actually go to a shop. Thanks.
