Cell Phone Guidelines - link to the article.
Four “new norms” for kids and phones:
No smartphones before high school. (Flip phones are fine.)
No social media until age 16.
Schools should ban phones during the entire school day. Just put them into a phone locker or Yondr pouch.
Finally, we need to give our kids more independence, freedom, and responsibility to play or hang out with one another on their own in the real world, just as most of us did when we were their age.
