I too have had good experience with IFS, and I think from the point of view of IFS the less 'solid' and more transient the parts are, the better. The traditional 'multiple personality disorder' are then excessively rigid parts that block each other. I do enjoy asking my friends how old they feel just in the moment when they talk about something benign bothering them. Most of the time people are able to pinpoint the age from which they speak. E.g. they had a situation that reminded them of some injustice they experienced when they were 6, and so they traveled the affect bridge back to the behaviours and attitudes they had at 6. Of course a six year old can't solve it, but just remembering that they are older and more capable now can bring back the 'adult' parts that can find a solution.
