Absolutely answering the question @Maggie.

I am aware from my reading that some psych's don't believe in DID ..... and issue meds to try to solve the problem ??

Do the littlies have names that they introduce themselves by ?  I am wondering whether someone could be switching imperceptibly, and you only know that there is a difference in mood and values and personality, but they are still identifying as the same person .... not announcing in any way that they are a different entity ?

Maybe that is too hard to answer if it is outside your experience ?
