This might be a triggering topic for some as there are mentions of neglect.
She is a wonderful 1 year old that has taken the brunt of neglect. She is unresponsive and will not connect to others inside or out. Most of us have heard about those "orphanage babies" that don't answer when you call for them, don't give eye contact, don't reach for things and so on and so forth. This baby has been exactly like that.
On the inside she lives another young child (a 2 year old) that is relatively social and who tries to engage her very often. She also lives with Lin who is an adult caretaker (who she calls "mama") and Lin's special child - Anastasia who is 5. She has a good 24h cycle and she gets cleaned, fed and all such things babies need. But she still doesn't connect. She has a teddy inside and she will respond to that from time to time, but otherwise more or less nothing.
On the outside, when she fronts, our SO tries hard to engage her in play, eating, touching different textures, singing etc. Anything she can to catch her attention. But nothing has seemed to really work.. Until now

We got a baby doll (just a regular plastic baby doll) that we named the same thing as the baby and my SO made a bed for it in a plastic bin on our dresser and talked to it when we sat there, saying soothing things or singing to it etc. At first we bought the doll so that another alter who has a baby doll would be able to play with our SO more easily, but it quickly seemed to affect this little baby. After the first 24 or so hours the baby doll was gone. I don't know where it went but in our communications journal it said, simply "baby sleep good. not touch baby so much" and it was put where the baby doll had been. This was our sign that the baby had caught this - she knew we were trying to reach her. So we found out that when our SO picks her up and talks to her, the baby wakes up inside. So now we try to match it with the 24h cycle that is on the inside so we don't wake her when she's napping etc. Sometimes now someone will come out and hand the baby doll to our SO or walk up to her and say "baby is awake" or "baby is scared" and she will take care of the doll for a bit, and the baby is usually soothed.
Yesterday we went a step further and had the baby be with us when we were forward so not only Frankie, a 3 year old alter in our system, got cuddles but the baby did as well.
Just wanted to share something that worked for us with an alter that has given to response at all until now. It might not work for anyone else, but it can be worth a try at least
