How would you handle this?

Depending on what it was they might be able to refund you. My 5 year old bought a game on the xbox a couple month ago. We contacted them and explained what happened and they refunded it. We also added a password to all of the eshop on our consoles so it wouldnt happen again.

I would definitely put a lock on downloading apps if they aren’t free apps. If it was like off the app store then I would just contact apple about the misunderstanding or even your bank to void the charge.

Definitely contact them, give the details, and see about a refund. Passwords are a must!!!!

My 5yr has a wifi phone and we use an app called family link. I can control her phone like awake time, downtime, time limit, I HAVE to approve apps and purchases. So if shes on a game and decides to purchase something then it alerts me and ask for my approval before continuing.

My kids are not allowed on my phone because I dont want them on certain apps like social media or regular YouTube, etc.

You can definitely get a refund, check your emails/Apple account or in your subscriptions on the App Store.
Does she have faceID on your phone or know your password? You have to double click the lock button and use faceID/password to buy things so I don’t see how it could be an accident.
Maybe try getting into the habit of using guided access and use a passcode for it that she doesn’t know

My daughter ordered some Ed Sheeran POP toy off Amazon last year that was $150 because shipping was astronomical. She had no idea that she clicked on it 😂 We explained the rules to being on her Dad's phone--may only click on the game apps he has downloaded for her-- and haven't had an issue since.

If you're going to give her a device it needs to be one that's totally locked down. Aside from the buying things she could accidently find all sorts online 😅

Dispute the charge on the card (debt or credit). Your child isn't an authorized user, so they should remove the charge.

As far as her ordering something I'd have a chat about money, impulsive decisions, & consequences. And absolutely add a password to all devices if they don't already have one.

Don’t give your phone unlocked to a kid. Use guided access on iPhone. It will lock her on the app you hand to her. Also set up password and biometric/face verification for purchases.
