Im sorry but no one can answer why someone keeps talking about a mommy to you. only you and your treatment providers can say that.

what I can say is that I never had any alters talking and wanting a mommy. my alters were dissociative/ trigger related. by that I mean I would encounter a trigger then have my dissociation symptoms then the alter who's sense of agency it was to handle that trigger would be in control to take care of what ever was triggering me into having my dissociation symptoms.

suggestion maybe you and your treatment provider can find out what your dissociation symptoms are before you hear that someone talking about mommy and wanting their mommy. this will tell you how and why they are doing that.

again only you and your own treatment providers can say why this is happening to you.

another suggestion if this continues to bother you contact your treatment providers.
