Are you certain he doesn't want to talk to your littles because of his inexperience/discomfort being around children in general? Or could it be because he doesn't think it is therapeutic for you to acknowledge and talk to the littles? I have heard that some therapists believe that if they don't acknowledge or talk to alters--basically ignore them--then they will extinguish themselves and the client will come to therapy with other problems to work on. I totally disagree with this approach. It seems hurtful and damaging, but I have heard that some T's don't even believe in DID and their method of dealing with clients who say they have DID is to ignore the client whenever she brings this up.
Can you discuss this openly with him so that you are very clear on why he is rejecting your littles? If he says it really is because he doesn't know how to relate to children, you could ask him what he plans to do to get over that. Perhaps he could volunteer at the daycare center at his church, and work on getting comfortable with children. Or take a course on "play therapy" at his local university. Or make an effort to spend more time with the children/grandchildren of his siblings. (I am assuming he is not a parent himself or he would be comfortable with children.) If, on the other hand, he says rejecting your littles is really part of his therapeutic approach, then at least you will have the facts and can decide what you want to do (try to convince him to acknowledge all parts of you, leave therapy with him, etc.)
Best of luck. How hard for you.
