Mine too. My oldest does so during periods of increased anxiety knowing that it increases their stress level. I do think young people become more self aware as they age.
My youngest very much limits his phone use, I think only accesses it a couple times a day in a scheduled way. He also recently asked us to change the passwords on our shared streaming services so he would not “waste time on movies/shows” (his words, not mine)
And I spend way too much time on CC.
