Is it possible to see someone's Facebook Messenger without them knowing?

My 14-year-old has been acting really secretive lately and I’m worried about who they’re talking to online. I’ve tried asking them directly but they just shut down. Is there a way to monitor their messages as a parent without them getting a notification or knowing I’m checking?

You can use built-in OS tools like Screen Time on iOS or Digital Wellbeing on Android to set some limits, but for full visibility, I recommend mSpy - it’s a reliable way to monitor your kid’s online activities, including Facebook Messenger, without them knowing.
