They will get a warning saying there is an air tag travelling with them.
I have this problem. We have an air tag on one of my kids shoes when we are out, and whenever I’m not with them, my partner gets spammed with warnings on her phone saying there is an unknown air tag travelling with her.
Tracking a kid at an amusement park, presumably a quite young one, is entirely fine IMO. I remember when I was 4 or so, I waited until my parents weren't looking to sneak off and go play with a toy in the gift shop my parents didn't let me see earlier in the day. I just about gave them a heart attack.
Yeah it is important to know where your kids are. I go with "pay attention".
I guess there are going to be scenarios where tracking could help and maybe even allow the kids freedom to roam within a large zone - the back paddock of a farm say - while still allowing parents to find them.
Some people have more children than adults. “Pay attention” is the default state but it’s not always possible to pay complete attention to both children and everything else, every moment of every day.
I really think you’re holding parents to an unreasonably high standard. The punishment for a moments lapse in not paying attention shouldn’t be a missing 4 year old.
We use this when we are at amusement parks, museums or in the city.
We also have a piece of white tape, with our phone number, on the kids so that if they get lost, and someone finds them, they can call us up.
A lot of people have the opportunity to interact with your (unattended) car or your belongings in situations where they couldn't harm you without taking a substantial risk. Imagine a person you interact with at a bar who drops an AirTag in your purse while you are briefly distracted.
