Helpful thinking for parents

I am only new here, so have only just started learning based on what I have listened to from the podcast and the material that is available here so far (won’t officially start until October).

What I am interested in finding out more about is how I can apply this knowledge in my role as a mother.
From what I have gathered – you can’t control another person’s behavior or thoughts, only your own thinking and that other people can do what they choose to do.

I know there are exceptions regarding your children and I wondered if you could please clarify them for me and if you have any other additional advice regarding helpful thinking for parents?
Many thanks!
