I am a mother of three young boys my self and couldn't agree more with everything you are saying. To all of you out there please remember he is only a young boy, don’t scar his life and his sister life. Don't be so quick on pointing fingers on whose fault it is and who should pay for it. Use Wiz's... advise emphasize boys role in being a big brother and what that means, give him a sense of responsibility in caring for his younger sister but make sure he understands the boundaries. If you find that professional help is steel need it make sure it is confidential? May love and understanding be your guides?
