DD16 got a new phone a couple of months ago. An Iphone 16. At the moment she pays just £5 a month towards it (with the clear understanding that this will increase when she gets a job). DH & I pay £40 between us. DD gets £25 a week pocket money which she is always complaining isn’t enough. She’s now asking us to shell out £15 for a magnetic ( I think) charger to use in the car on a 4 to 5 hour journey & refusing to buy it herself. She uses Spotify constantly & claims that it drains the battery, so our suggestion of charging her battery fully before we travel might not be enough. DD has mental health issues & her music is a form of therapy. She’s trying to guilt trip us by saying if her phone dies when she’s out & about then she’ll blame us. There’s a festival coming up where we will need to be able to track/contact DD. Tickets already paid for. How would you handle this situation? This sort of thing comes up a lot, with DD believing she shouldn’t have to pay for stuff.
