A Child Called "It" chapter 1

I just started a new book called A Child Called "It" written by Dave Pelzer.I've heard from friends and family that this was a very good book.When I read the first chapter I wanted to cry how could a mom hurt her own child like that I mean its just horrible. I could never make my child starve or beat him.The child's name is David and him mom is really mean to him.If he doesn't complete his chores he wont be allowed to eat and if he does he gets scraps that the dogs wont even touch or want to eat. In this chapter the principle and teachers try to help him and a police officer does too.And they find a way to rescue him,Which made me really happy!!
