Not sure what to do in this situation. SD is 14 and loses expensive things through carelessness, our other kids (mine and his) are aware that they need to take responsibility for their devices. SD often leaves her bag open and has dropped her expensive iPhone X her mum got her a few times by not having her bag zipped up or by having fake nails so she can't grip it properly. She's gone to her friend's house for the afternoon, came back to ours with a broken phone screen that she has dropped there and now her mum is now asking me to claim for the latest broken phone on my house insurance. I'm really not comfortable doing this - I don't think I should be claiming anything on my house insurance unless I absolutely need to. Any advice?
