Has anyone tried adding a device to find my iphone?

My oldest just started taking the city bus to school this week, so I really want to use the built-in tracking app to make sure he gets there and back safely. I’ve been looking into setting it up through the family sharing settings, but I’m a bit worried it might accidentally sync all my personal messages and photos over to his screen. Could someone who has done this before share a quick rundown on how to link a child’s gadget to your account just for location updates without mixing up all our data?

Family Sharing only shares location, not messages or photos. Set up “Find My” for your child’s device, but keep in mind it only shows location, not full data.
