Goal: Speak in a soft voice to my son when upset or frustrated. I will not lose my temper. Plan: Take deep breaths before reacting. Walk away if feeling angry. I will validate his feelings.
Is something like that on the right track?
Yes! Yes! Yes!
But can you zoom out a little farther in your "Goal". For example, I could see something like:
I want to be a better mother to S4 - I will not lose my temper - I will validate - I will speak softly and so on and so on
I think this gives you some freedom to focus on a few categories and hone in on how you want to be.
