The #1 job for a parent is to make sure their children are bored out of their minds regularly. Take away the sources of easy serotonin (usually the smartphone), either by taking the kid outside without it or whatever works for you.
For example if you're on a 20 minute car ride as a family, the kids don't need to be on their smart device every second of the way - preferably at all. It's OK to be bored and just have your own thoughts to keep you entertained.
