A Child Called It - Author Purpose

"My relationship with mom drastically changed from discipline to punishment that grew out of control. It became so bad at times, I had no strength to crawl away...even if it meant saving my life." Dave Pelzer, in this quote, chose to use these words to describe how intense and abusive his relationship had got between him and his mom. He started off with simple discipline and they were turning into severe punishments. When he says he couldn't crawl away, he meant that he didn't have the strength to get up to walk or away or break free. He felt that in some times, he was going to die because he was so weak, so he had to take every severe blow that was passed to him.
