Is there a way to see my child's past locations on their iphone without them knowing?

My teen has been acting suspicious lately and I’m worried about their safety. I know their iPhone tracks location history, but how can I check it without them getting a notification?

Short answer: not really—Apple doesn’t let you pull a location timeline remotely, and anything “stealth” either needs physical install and shows a profile, or gets caught by the location arrow. Past spots live in Significant Locations on the phone (you’d need their passcode), and for ongoing tracking the clean way is Family Sharing/Find My or your carrier’s family locator, plus a quick chat and some Screen Time ground rules.
