Started praying with my kids every morning before school
Been doing it for like 3 months now and honestly it's changed the tone of our whole house. Nothing crazy, just 5 minutes where we each say something we're grateful for and something we're asking God for. My 9 year old prays for the homeless guy she sees on the way to soccer practice. My 12 year old prayed for my boss when I was stressed about work. It's teaching them to think outside themselves. Plus I actually feel more connected to them. Wish I'd started this years ago.
That's really cool. We tried this for a while but kept it lower key - more like just a moment of thankfulness at breakfast rather than formal praying. Both ways work I think, whatever fits your family.
