Sometimes I have to take a deep breath and let the lesson goal for the day slip away while I take a walk with a grumpy child.
Making time for fun and relaxation with the kids, whatever that looks like for them...for me that takes a conscious letting go of something else since there isn't usually time in the day to hit every academic goal and relax together. This might not happen every day, but I try to keep it on my radar.
Making accommodations when something is stressful for them, like reading it aloud to them or letting them use a calculator...valuing their state of mind above the academic.
Sally Clarkson has a lot to say about relationship. And there's a new book you might like called
Teaching From Rest. I've only skimmed it, but I think you'll find a focus on relationship.
I want to come back to this when I have more time. This is a favorite topic of mine.
