some locations limit what diagnosis's can be used on children in that location. many places in my state do not diagnose DID in childhood. just like they dont usually diagnose Bipolar disorder in children in my location.

regardless of diagnosis the treatment is the same. teach the child to focus on things outside their self (grounding, breathing, meditation, medicine for anxiety and others just like with adults) work on problem areas like behaviors,

it is actually harder for children because they dont have the mental concepts and logic that adults do. you cant just tell a child that voice in their head is an alternate personality and how the brain created that alter by this that and the other thing physically and mentally and... well think about all the different questions you have had over the years of your adulthood that have been answered for you including all that you went though with integration of your alters if you are integrated ( I cant remember who is and isnt with out going back to reread your posts ) now think about trying to explain all of that to a child and have them understand everything.

children just dont have the ability to understand the abuse they went through that created their alters let alone the mechanics of mental disorders and healing from this.
