Praying with my kids before bed changed everything
Started doing this about 6 months ago on kind of a whim. Just simple prayers, nothing fancy. Let each kid say what they're thankful for and what they want prayer for. My 7 year old prayed for our neighbor who's sick, my 4 year old thanked God for his dinosaur toy lol. But something about that 10 minutes just shifted the tone of our whole house. Less fighting at bedtime, they actually want to do it. My wife said she can see them being more thoughtful about other people. If you're not doing this yet, seriously try it. Game changer.
Six months in and you're already seeing the shift. That consistency is what makes it work. Sounds like you've found something really special.
