I completely agree and am surprised at the responses to your comment.

Personally, I'm waiting on a call about an adoption, and I can't ever leave my phone until that goes through. Even before cell phones, parents would leave a number for the babysitter for where they'd be. Yes, kids were raised without phones before, but I'm sure it wasn't a better situation when parents got home and found a note that their kid had to go to the hospital or something. People may say this is fear-mongering, but I guess they don't have kids with health issues.

If you don't want to be distracted, there are features like Screen Time that can lock you out of every app except phone and messages if you want.
