Do NOT wait for your husband to start disciplining his children - he's already proven that he will not do it and sees nothing wrong with their behaviour! Like a previous poster said, get them to a doctor now! And stop off at the police station after that! Press charges. Against those boys and your husband (for doing nothing to protect your children). And get out of that house! Even if you have to go to a shelter to be safe. Please do so immediately. You can stop to think about what to do next when you all are safe and things calm down.
