I'm not able to see or make one, so have looked at spacekraft or sensory direct websites. There's quite a price difference between the two, I wondered if anyone had any experience or could advise where is best to get one from? Looking at DD's body weight of around 18kg it would only need to be 1.8kg so prob a 2kg one is the nearest I'll be able to buy. I'm hoping kg to get one I can leave on all night without fear of overheating, as she's 5 I'd assume she will just be able to push it off anyway if she got too hot.
