Creating alters (alternate personalities) in dissociative identity disorder (DID) is a helpful way to deal with different personalities. I don’t know exactly how to tell someone to create an alter, but it seems that when there is a need for one, it will come to be. One such time was with my little girl alter. Her name is Colette, and she is five years old. Colette taught me about creating alters with dissociative identity disorder.
