I found it helped my boys to write when I started the session as a fun, family thing. I would say a sentence, then start the timer, usually for 10 minutes, and we would all free write based on the sentence. Then we would share what we wrote if we chose. They never chose not to read theirs aloud. And sometimes deep and hidden stuff would come out.
That is interesting to know. When I re read it the following day, I felt there was much more emotion I had naturally omitted... those pesky survival instincts <3
