Question about Alters and living with them

So my whole life apparently I've had Alters and it wasn't until just recently that I was diagnosed with DID and now I'm acutely aware of the different fragments of myself and the other day while doing some Shadow work the others yelled at me when I tried to access my child side like got violently angry with me and the protector came out and said that he wasn't allowed to come to the front. 

But I was in the process of getting things that like reminded me of my childhood and I was really excited in the fact that it was making me happy on a level that I didn't quite understand

and it was just like a brief glimpse at this child playing with a toy and four of the seven that I know of stepped in front of that vision and when I asked about it I was basically told that the kid was off limits. 

All of this is so brand new to me and strange and trying to circumnavigate all of it. Has any of your Alters reacted like that to the system, or while trying to understand them better? I still went through with getting the item and was happier than I had been in awhile and felt content, but still like there was some guarded aspects to it.

I've started becoming aware of when I'm switching vs when there's a "copilot". And my "default setting" was named "Main Me" by the others because it now feels like a bunch of people sitting in the "front seat" then depending on the situation friends in if I get bucked and one of them take over.

My therapist is excited with my progress and that I've already been in communication with the others and that I/we have figured out some things by ourselves. But it's still hard for me to talk about them like they're other people vs being a part of my collective whole.
