I Spy on My Kids' Social Media

I'm an at-home parent to three kids aged 10, 13, and 16. I know it's not exactly the most trusted behavior, but I check their social media pretty regularly just to stay in touch with what they're up to. I tell myself it’s for safety reasons, to see if anyone suspicious is trying to make contact or if they’re being cyberbullied. But honestly? Sometimes it’s just curiosity getting the better of me. What kind of videos are they making behind my back? Who's this new friend? Are they posting embarrassing photos from family outings that I'll have to take down before grandma sees them? It's not exactly a healthy habit, but it sure feels like peeking into their world gives me some peace of mind.
