> We limit screen time pretty aggressively, but it's getting harder as they get older.

Curious into what kind of example you as a parent are setting in limiting screen time for yourself. For me, it's easy as I'm an old fart that has had a longer time without devices than with one while also not participating in the socials. We now have parents that have had a device for the majority of their life having kids that will never know a time without devices. So this is an honest bit of curiosity at the risk of sounding judgemental.
