Do you do it?
I'm a bit funny about leaving things on overnight, generally, so naturally leaving a fan on all night in my 4yo bedroom puts me uneasy and I'm sitting on my hands not to go and turn it off and put it away now. It's on the floor by their bed and behind the bedroom door if that makes a difference. There is a trailing cable. I think this is partly why it makes me nervous and wanting to put it away. They've had he fan on since 8pm ish.
Kids bedroom is in a loft conversion so very well insulated. In the summer when the temp spikes, little one will be having sleepovers in younger siblings bedroom (coolest room in the house) to cope with the heat!
