At what age should parents look through their child's phone?

My kid just turned 13 and I’m not sure if I should still be checking their messages. When did you guys stop or start?

Hi clutcher_gg! What worked for us was starting gentle checks around 12 and gradually giving more privacy as trust built up. Even now with teens, I use Eyezy to discreetly keep an eye on things without making them feel spied on. It really helped us balance safety and independence!
