Hello Frustrateduser2870,
Thank you for using Apple Support Communities. Sounds like you want to track or kids using their Apple Watch. If so, you'll need to use Find My in order to do so. The resources below can help guide you on how to accomplish this:
1.) Find people and share your location with Find My - Apple Support
When Share My Location is turned on, you can share your location with friends, family, and contacts from your iPhone, iPad, or iPod touch with Find My. You can also share your location in the Find People app on watchOS 6 or later with Apple Watch models that have GPS and cellular and are paired with your iPhone.
If you already set up Family Sharing and use Location Sharing, your family members automatically appear in Find My.
2.) View a friend’s location with Apple Watch - Apple Support
We hope this information helps you. Thank you for using Apple Support Communities. Take care.
