Recently got dd2 one of those galaxy projectors that beams a night sky onto the ceiling. She loves it. Just wondering if it’s safe to leave on all night? It’s good for her room not to be in total darkness in case she wakes up, but with it being new I’m unsure about it overheating. I got it from Tik Tok so not entirely sure of the origin. It’s got an USB still cable that fits into the plug. Any ideas?
