From my own personal experience with 15 alters ----- some of the little ones just wanted to know that someone cared for them and that they were finally safe. I reassured them often.....
Have you tried talking to them like you would with any other person who was upset or angry? Do you personally try to calm them your self..... in times of calm? Do you have a mental safe place they can go to and learn to be secure in when they are there..... and have fun activities for them to participate in when in the safe place?
