I am trying to decide what you feel a mother should do when she has a child. Give birth and then shut everyone (including husband/boyfriend) out of your life until the child is an adult? Not working, no visiting friends that you haven't known since childhood, the only company she should have is her female family and her child?
Sorry, but almost everyday you have to leave your child. (to go to work, meetings, church etc.) In this day and age, most families need a wife/mother to work for the family to exist financially. Not everyone has suitable female family members to leave their child with. Not everyone is still best friends with the little girl they met in first grade. Not everyone has suitable family/friends who are willing/able to babysit for a mother.
So for a mother (single/married) to have a life she will have to leave her child's side at times. In this case it was to go downstairs to do the laundry- she didn't even leave the house. Even family/friends in this case had noticed no problems with this . I don't know how she had missed the previous sexual abuse of her dau but I do believe that she did. (Maybe he had molested previously- but didn't rape until that night).
What I do believe is that this mother is not at fault, from what we know at this point. She was caring for her child, and with someone who she had found no reason not to trust. This B/F turned out to be someone she couldn't/shouldn't trust, but by the time she found this out it was too late.
I won't blame the mother at this point, because I believe that she was just trying to have a fulfilling life with her dau and things went tragically wrong.
The blame lies with the who thought it would be exciting to rape a baby. Then to beat the life out of her because she fought back. This mother will feel the loss/guilt for the rest of her life, merely because she invited the into the house to spend time with. But in reality- we can only control our own actions- we cannot control the actions of others, and we cannot know what thoughts/feelings that others have if they keep them hidden from us.
