it will b hard but i wud let them be. Just like being a parent, u have have 2 sit back and watch ur children get burned, so that they learn not to touch the fire. parents also need 2 be burned sometimes. if the situation gets 2 violence, (physical or verbal) step in and tell ur mom how u feel. if it gets 2 rape or sumthing serious call 911 no matter what u think ur mom will say. she will thank u eventually
