Is it possible to set up parental controls on iphone text messages?

I’m trying to limit my teen’s texting but not sure if iPhone lets you block or monitor messages. Anyone know if this is doable without them noticing?

Hey there! Lots of parents wonder the same—I like to think of monitoring as another way to keep our kids safe, just like seatbelts! iPhones don’t really let you read messages directly, but many of us use mSpy for discreet monitoring—it really helps give peace of mind!
