Maybe don't? That's creating unneeded attention to your child coz it's unusual for child to have expensive devices.

Omg, it's even scarier to think that people can easily profile you through your kids with what they're wearing. Kidnapping would also be a possibility. Stop thinking Apple devices are life saving devices. There are many more devices out there that could work the same way but just without the Apple logo. Safer that way.

I'm sorry if this is not the answer your looking for.

Can your kid wear it to school?

The only apple thing I will pun on my child is perhaps an airtag.
