Reading Jonathan Haidt's 'The Anxious Generation' broke me. I have two kids, still far too young for smartphones, but his book and all of the surrounding research has made me DRASTICALLY alter the way I use my own smartphone and will shape the way I treat phones with them.

If you have kids, take the "wait until 8th" pledge: https://www.waituntil8th.org/

No smart phones until after 8th grade.
