Earlier quoted context omitted.
I have found few things as freeing as removing slack from my phone, especially at the playground - i enjoy the time i spend with my kids more.
To me, being at the playground is not a prime example of spending time with my kids. I'm fine with replying to some work related messages while basically watching my kids play. Playing soccer together, reading to them, playing a board game, doing a joint Lego construction project, learning them to skate, etc. That's spending time together. It doesn't mix well with work.
What activities mean what depends on the kids age a lot, and the kids and the parent. We agree that spending time together doesn’t mix well with work.
