I’m worried-does anyone know how to check my kid’s instagram history?

My daughter is 13 and I’ve noticed she’s been really secretive about her phone lately, staying up late and hiding the screen whenever I walk by. I tried looking through her phone directly but she has a password and I don’t want to invade her privacy more than necessary - I just want to make sure she’s not talking to strangers or seeing inappropriate content. Is there a way to view her activity or at least get notified about what she’s doing on there without her knowing?

Careful going full ninja, or you’ll end up like my wife trying to secretly check my browser history to see how many Steam games I just bought! I’d ask “why did the phone need glasses? because it lost its contacts”, but hopefully she’s just hiding silly memes, because finding where my toddler stashed my Xbox controller is already enough of a stealth mission for me.
